Replacing the A/C Blower Resistor on a 2009 Ford Escape

The A/C system of the Ford Escape has a resistive sensing element used regulate the blower motor.  If you find that the A/C blows air on some fan speeds but not others, it is likely that the blower motor resistor has burned out or otherwise failed.  On my 2009 Escape, the blower motor would run in positions 3 and 4, but not 1 or 2.  Based on other reports online, failing for the low speed settings seems to be the most common symptom.

Replacing the resistor on the 2009 is cheap and simple, but since I could only find photos for the 2008 Escape, I took some pictures while my dad and I replaced the part.    I replaced the defective resistor with this part from Advanced Auto Parts though it is available from multiple distributors.  My Escape does not have automatic temperature control, as the temperature is set using a cold/warm knob and not via a digital temperature set in degrees.  You may need a different part if you have automatic temperature control.


  1. Open the glovebox and empty it out.
  2. Near the top of the glovebox left and right sides, squeeze inwards gently to allow the glovebox to fully extend.
  3. The resistor is inserted into a slot towards the right behind the glovebox and fastened with two hex-head screws.
  4. Remove the screws with a 5/8″ socket and detach the harness.  I found it was easier to leave the harness on until after removing the screws since it kept the wires out of the way.
  5. The keying on the original resistor (left) and new resistor (right) did not match, so I had to drill out two holes along the top.  Make sure to completely open the key holes so that it clears the alignment keys during installation.  I’m hoping this is so that the same part can be used on slightly different models, and not that I have the wrong part.
  6. Re-install the resistor into the slot.  When fastening with the screws be careful not to cross-thread the soft plastic or over tighten.  When trying to locate the screws by feel, they will go in the front-left and back-right holes looking from the passenger seat towards the resistor.
  7. Reconnect the harness.
  8. Test the A/C system for each blower position to verify that the replacement is working.
  9. Set the glovebox back behind the stops and remove the dog from the passenger seat.

  1. I’m pretty sure I have this problem. I have a 2009 Escape. My fan only works on setting 4. I noticed it driving home tonight in a snow storm. Your posting was perfect.

      1. Hi, I tried this process and replaced the AC Blower Resistor today. Unfortunately, the problem didn’t go away (only the 4th speed works). What should I try next? Or is it possible i bought a bad AC Blower Resistor? Thanks in advance!

        1. Hi Chris. Sorry to hear that. I’d guess that it’s unlikely you happened to get a bad one that has the exact same symptoms. If you have the original resistor, the new resistor, and an ohm-meter, you might be able to find some differences between the measurements made on the original and new one. I haven’t had any luck finding a schematic of one of those resistors, so I’m not sure what they should measure as. It’s also possible there’s something more significant that’s gone wrong, but I’m not sure where you’d look next. Let me know how it goes!

        2. Same issue here my 08 has position 4 fan speed only. Thanks this saves me a headache. So you are not alone. At least it works. I had a Chevy where it flat out quit.

  2. RU1333 was the correct part, $20 here in Canada. Getting 2 screws out was hardest part, 18 mm socket. Perfect fix, no issues, thank you very much. Undoubtedly a $100+ fix at dealer.

    1. It works!!! Just a couple tidbits from my own experience. I have a 2008 Escape Limited WITHOUT automatic temperature control, so the part was the one linked to at the start of the article. The screws to remove the part are 8mm and I found working with a 1/4″ socket wrench was easier. Thank you Louis for posting this.

      1. Thanks all information from your guys.
        I have same problem of 1, 2, 3 not working only 4 working for my 2008 Escape.
        Today I asked on garage store, got quote of $250.
        I would like to do by myself as you guys.
        Would someone tell me where can I buy the resistors?
        Thanks in advance

        1. It was available online from Advanced Auto Parts, though you may be able to get it in store. I’d call ahead to make sure it’s in stock.

  3. I went to napa auto parts and bought the piece. I predrilled the holes as instructed. With the help of my fiance we replaced the part and it works!! Thank you so much. The part and labor cost me under $25… which is much less than what others were charged at the dealerships and auto repair shops.

  4. Hi Louis, Thanks for posting this. Worked perfect! $26 and 9 min later, it was done! Would’ve been even quicker if the darned thing wasn’t in such a hard to reach, awkward place. Thanks again! Would’ve likely been a couple hours and $100+ at a shop.
    Just for reference, I have a 2009 Ford Escape w/o auto temp control, so it was exactly the part you linked, BWD RU1133 Resistor/Resistance, and bought it at the local Pep Boys here in CA.

  5. Thanks so much…..I talked to a mechanic and I learned more here than from what he said. I could just see the $ adding up in his mind. My brother and I will tackle soon. :)

  6. Ahahahhah, it wasnt working so I did a fonze and tapped it with the wrench and it went on thanks for tip, its working , so anybody that replaced this part and it doesnt do anything give it a tap mine popped right on.

  7. Great fix, worked when my blower only worked on setting 4.
    I found the connector would not click on the replacement resistor, so a bit worried it will shake off.

  8. Thanks for the write-up! I have a 2009 Escape and the resistor just went out for the 2nd time. Took it to a shop last time, for 2 days and several hundred dollars. This time, I decided to give the repair a try on my own. After reading your instructions, it took me a half hour and $22, including the trip to Auto Zone :)

  9. Hi,

    I just found this thread and I am having the same issue with my 2008 Ford Escape. Heat/air only blows a little on 1 and the same amount of “little” comes out on 2 and 3 then blows full blast on 4. I took my car to get it fixed and they said it was the resistor. They charged $120 replaced my resistor, gave me my car back… And the air and heat worked exactly the same! I turned my car around and took it back to the dealership immediately. I told them the issue was not fixed. They looked at it again and said it was now the knob. I left my car with them again and later received a call saying they decided it wasn’t the knob, but a part in the knob and would be $400 for the part alone.

    I’m not totally convinced, given their lack of fixing the issue the first time, that this is the issue. Does anyone have any advice or information on this problem or what it could actually be? I’d appreciate ANY help, as I’m not keen on paying hundreds of dollars for them to try to figure out what MIGHT be the issue to fix it. Thanks in advance!

  10. I lost the High speeds on my wives 2007 Escape a couple years ago and replaced the resistor and it fixed it. Just a few weeks ago I lost the low speeds on my 2008 Escape and just replaced it again and that took care of my problem as well.

    All I can think of is that they actually did not replace the part or got the old part and the new part mixed up which would explain the same issue still there. I would fix it myself and demand all my money back from the shysters!

    BTW – You can get the Mazda Tribute part or the Ford Escape part for these same years – same basic part but you do have to drill out the holes to match the ones that are open on the old one. Use a 3/16″ drill bit to do it. BTW – The screws that hold the part in are 8mm hex heads – not 5/8″ like in the write up or 18mm like another comment had.

    My Directions would be: Squeeze the sides of your glove box to get the tabs on the sides (in the back of the glove box) past the opening to allow you to let the glove box come down in order to get at the fan housing where the resistor is located. It will be up and to the right side as you look into the space that is now open. There is a wire harness going to it. You can see the front screw but the back one (kiddy-corner on the resistor from the front one) you might not see too well. Use a 8mm standard length socket on your 1/4″ ratchet to take out the screws. Remove the Resistor with the harness attached by pulling the harness/resistor straight up. Once free of the slot you can pull it down a bit and then you can depress the little tab on the front of the connector (the part that faces you) to let the harness connector come loose from the resistor. Now the resistor is free and you can take it out of the car for the next part of this repair.
    Now take the new resistor and match it up to the old one and see what holes need to be drilled. (you might want to be sure you know which one is new and which is old so you put the right one back in)
    Drill out the plastic in the indented hole spaces to match with the old part (the indents make it easy to put the drill bit exactly where it needs to go – its takes only seconds – easy to drill and goes very quickly. I had my 6 year old neighbor boy drill them out it is that simple)
    Once the part has the right holes you can now install the new resistor. Connect the harness to the new resistor by connecting back up with the harness / wiring connector – insert the resistor in the slot by going straight up to get clearance and insert straight down into the slot/space – Now put back in the screws and tighten them but just to where they get tight – (do not over tighten).
    Now you can put your glove back in place by pulling in the sides a little to let the tabs go back behind the panel and you are done.

    My cost – $23.56 with tax for the part and 15 minutes of time!

  11. 2009 Ford Escape….air does not blow on any setting, tried changing resistor and nothing. When I have the control set to cool and have re-circulate engaged while driving the air is cold but not blowing. Now what?

  12. Thanks for the detailed steps. My AC works but the fan doesn’t blow on any speed. I have a 2010 Ford Escape. I replaced the resistor and the problem didn’t go away. So I decided to tap it hard with my hand underneath the glove box, and the fan comes on. At least I now have a work-around. If anybody finds out what to replace to fix my issue, please post.

    Thank you.

  13. Thank you for this tutorial, it worked perfectly on my 2009 Mazda Tribute and we now have fully working air. Took me about a half hour and under $25 for the new part from the parts store. The dealer had quoted me $260 for the repair job, so glad I googled it and found your tutorial. It’s gonna be a ribeye steak and Stella beer weekend for me with the money I saved!
