Acura TL Blower Stopped Working: Fix

How to Repair Blower Motor Issue

Time Required: 20 minutes
Tools Required: Phillips screwdriver
Cost to Repair: $45.00

Description of Problem
Last week the blower for the A/C and heater stopped working on my 2003 Acura TL Type-S. The climate control unit will turn on, but you cannot feel the air because the blower will not blow. I tried turning it on Full Auto in both the hot and cold settings, nothing. I turned the fan knob to max and still nothing. When you turn the climate control unit on, you can hear the compressor under the hood turn on. The problem is clearly the blower not turning on.

The Repair
After some online research, I learned that much like the seat heater problem, this too is a common issue for the Acura TL (as well as other Honda and Acura models). A friend had this same issue with his Acura TSX. The solution: Replace the blower resistor.

Disclaimer / Precautions
I am not a mechanic. Follow my advice at your own risk. This repair is easy and cheap- so don’t be scared. Be sure to disconnect the battery, wear safety glasses, put on gloves, tie your shoes, chew with your mouth closed, and any other safety stuff that makes you not sue me.

Let’s begin!

Most of the time, the problem is that the blower resistor needs to be replaced. But first check to make sure the issue is not something else like a blown fuse or corroded connector. The blower fuse is located under the hood (it is close to the firewall on the passenger side for my model). The fuse is labeled “Heater Motor” on the fuse cover.

If the fuse looks good, move on to the blower inside the car. The blower motor is located below the glove box. Notice the giant yellow arrow pointing to the location.

Here you can see the blower motor and the blower motor resistor.

Disconnect the wiring connector from the blower motor to make sure there isn’t any corrosion or connection issues. Sometimes corroded connectors [photo] will cause the failure. These are clean, this is not the problem… On to the blower resistor.
Blower Connector

Follow the wiring harness from the blower motor to the blower motor resistor. It is a white plastic trapezoidal-ish piece that is fastened by two Phillips head screws. Remove the two screws that fasten the blower resistor in place. This will allow you to pull the blower resistor down and disconnect the wires.
Remove Blower Resistor

Gently pull the blower resistor down and disconnect the wiring connector. Here is a close up of the resistor after it has been removed. These connectors look clean too.

The metal side of the blower resistor had some crud on it. I don’t know if this was any indication of it being broken or not.

Replace the blower resistor with a new one. This part can be purchased at most auto parts stores. I paid $41.99 plus tax at AutoZone. To reinstall the part, simply screw the resistor back into place with the two screws. Reconnect all the wiring and test by turning on the climate control fan.

It should work perfectly now. If you continue to have issues, you might need to visit your mechanic.

    2003 Acura cl. Your resistor advice was spot on and fixed me right up. You prob saved me $200. Thanks!

  • Danny

    Hey thanks for the great info I found the problem out was 2 wires going into the blower motor I believe thru were shorted out by touching eachother and pulled them apart and boom a.c.keeps on right away…my question is the 2 wires that were shorting out were really and I mean really hot even after they were no longer shorting out or touching one another is there a reason for this? Or should I just cut the wires and re splice them cause thru look real corroded. Any ideas or help anyone please would be much appreciated

    Thanks so much, found this tutorial online. Checked fuses and went straight to Auto zone and picked up 41.99 part. Back in business now!

  • k(Black)

    Would this be the same for a 1998 Acura TL?

  • Ped

    You are awesome!!!! I had the exact same problem in my 2004 Acura TL. I checked the fuse, as you suggested. Once I realized that the fuse was good, I went to auto zone and purchased the BloweMotor Resistor for aboit $49. It took me about 5 minutes to replace it. Now everything s back to normal. Thanks a lot.

    My 2002 TL-S had the same problem. I replaced a new blower resistor from Acura dealer, but I had the same problem as john Eagan’s post in May 2013, the fan keep running, and Josh did not have the answer. It turned out that the brand new part was defected. When I unscrewed the two nuts and left the blower resistor out of it socket, the fan controller was working fine. If I tighten the two screws back, the fan was keep running at high speed. The problem is the two tighten screws caused a loosing circuit board to shorten the circuit somewhere inside the resistor. I went to the dealer and got a replacement and it worked fine.

  • Dear Josh,
    I am having Acura tl 2000. My blower is workking but no there is no air flow from the ducts even if i change the mode.

    Checked the fuse inside the car first then the one under the hood.. went to auto zone part was priced just as you said. Installed part and heat is working again.

  • John

    This was Spot on advise. I loved your pictures fixed my 1999 Acura TL in 10 minutes paid $36.15 for part from Advance Auto Parts online and picked part up at store. If you purchase online they give a 20% discount. I will pass this on as well, I read on another thread that the evidence for failure for this part is that your blower motor will run continuously in the highest setting. That was my problem.
