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.

Disconnect the wiring connector from the blower motor to make sure there isn’t any corrosion or connection issues. Sometimes corroded connectors 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. If this repair worked for you, please leave a comment below and include the year, make and model of your Honda/Acura.

    I have an 01 CL that I couldn’t figure out what was wrong with. This was my first major fix by myself. I followed your directions! When the blower turned on and heat started to come out from the vents I almost jumped for joy. I was still on the ground when it happen. THANK YOU so much for this tutorial.

    My 03 TL was having the same problem. The connections to the resistor looked clean. The resistor looked ok, other than being a little dirty.

    I bought a replacement at a local auto parts store and it did the trick. I was surprised it work, but definitely cheaper than taking my car to a mechanic.

    Thanks for the article!

    Thx, I got it off ebay, but the repair didn’t work. It was so cruddy that I’m sure I would have had to replace it sooner or later so no worries. I will try replacing the wires for the blower mtor connector.

    Worked for me. Followed the above information and lead me to the load resistor and replaced as necessary. Many thanks for accurate information and save a bunch.

    Worked like a charm. Picked up blower resistor from O’Reilly’s Auto parts for $43. Thanks for the step by step instructions.

    I have a 2005 Acura TL. WORKED! Thank you, thank you, thank you! I had air blowing out of my vents at full blast, even when the display said it was off. I couldn’t get it to turn off! I read a bit about it online and decided to replace the motor blower resistor. Sure enough, thanks to your tutorial, it only took about 10 minutes and it saved me hundreds of dollars!!! The part was $50. In the 2005 TL the part is not white, but black, fyi. Thanks again! PS. I have the car skills of a turnip! If I can do this, ANYONE can!
