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.
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.
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.
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.
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.
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.
