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.

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.

    This was indeed the fix for my 2005 Acura TL. I had intermittent issues with the fan in the car. It finally just stopped working. Replaced the part and that fixed it. The location was a little different than the pictures but still was able to figure it out.

    Thanks for posting. Saved my $$$.

    Just wanted to say thanks I just fixed the same exact problem in my 2004 Tl it took 5 mins I got heat again ?

  • Abbe

    Thanks Josh, that is exactly what my issue was on my 2003 CL. I bought the part and my son climbed in under dash and unscrewed the part for me and I plugged in the new part and lo and behold I have air again! Thanks for the easy trouble shoot and posting of info.
    Great description. Super appreciated.

  • Greg

    This fixed my issues on my 02 acura TL. Saved me a bunch of money. Thanks so much for the walk through.

    Hi Josh,

    Thank you for an excellent description – I found the same problem in my Acura 2000 TL. My question is – how you disconnected the wiring harness for the blower resistor. Is there some kind of latch?


  • pam

    There is no sign of corrosion so chances are not it or should I replace anyway
