2004 TSX 130k
I've checked fuses and all are good. When I've had the blower motor resistor die on other cars the fan usually goes to high. The blower motor doesn't work at all this time.

This poster indicated that the resistor did indeed fix his blower motor:
https://acurazine.com/forums/1g-tsx-problems-fixes-128/ac-blower-motor-does-not-get-power-683187/

So I'm asking, does it happen that the blower motor will not work at all if the blower resistor stops working?

Here's a link to the OE part:

Thanks for any reaffirming replies!

The transistor controls the fan speed and works differently than the resistor on older Hondas.

The transistor changes the resistance on the ground side of the blower. A transistor can have the fan run at any speed.

A resistor changes the resistance on the voltage side of the blower, and is just 3 or 4 resistors in a series. The highest fan speed setting will turn on the fan, because the hot wire does not go through the series of resistors. The lowest fan setting will go through all of the resistors.

If you know how to solder, you can replace the thermal fuse and the chip that is inside the transistor. There is a temporary fix to bypass the fuse by soldering a resistor in there. Just search the web for those solutions.

As a follow up, the transistor did fix the blower motor.

The same thing happened to me two days ago. The AC blower was not working. so I followed the same thing and changed the transistor, and wollaaaaa. problem solved.
its an easy fix. if anyone needs the part number for future: 79330-SDA-A01 ( my car was 2004 TSX, without Navigation). but I think the part is teh same for all 04-08 TSX.

Was it simple to change out the transistor on your own? I have the same problem (AC BLower not blowing air)

I just changed mine too. It was pretty simple. I found a youtube video of someone changing it on an accord, which it's nearly identical. BTW, they sell these on eBay in the $20 range. I didn't want to wait and got it at the honda dealer 3 miles away from me...

So my 06 TSX A/C and does not start. Tried manual and auto, no luck.
I did what many posts told me - check relay, fuse. I checked power in Fan motor connector, HOT on White/blue wire, Black/blue no power. I opened resistor conenctor and checked, Again Black wire there has power, the other does not (total 4 wires of which 2 other wires are different kind int hat connector). I took out the Resistor and tested for OHM it showed about 1500 OHM.

Since I don't see power issue, I wanted to check blower .. many post suggested running a 12 V to the blower directly (I dont have a seperate 12 volt generator, so I am using the connector that comes thru fuse to Fan socket. I took the connector out from fan. I put the HOT side of conenctor to a tester cable and the other side of tester cable intot he Fan's hot side socket. I am using my jump cable to the ground side of the socket. Since I am using a tester as a cable in hot (I dont have electric cable at home), The tester light turns on .. telling me that the FAN socket circuit is ok. But the FAN does not run. Shouldn't the fan run?
Can anyone suggest how to do fan test and if the fan is the culprit here or not?

thanks

Finally found out that Blower Motor Resistor doesn't work.
The part number for 06 Acura TSX is 79330 SDA A01. Local Honda and Acura dealer dont have it. Honda price is 86+tax, Acura price is 101+tax
Can anyone recommend online site where I can get it?
Thanks

2004 T/L 135K Same issue. Blower intermittently would not turn on. After the car would cool, it started to function again. It's winter here so, good to get the blower back online. Thanks to all before me who posted the fix. The location mentioned was right on. Just above the carpet line pass side. need to remove the protective cover, to gain access to the blower resistor. Two screws and its out. I noticed upon inspection after popping the blk plastic off that the four corner solder points seems a bit discolored. Not sure if that was causing the intermittent functionality. Took all of 10 minutes. If that isn't the fix, I'll report back.

anyone have a solution for 08 tl. when i turn on ac and hit the fan adjust up, only one side works, whole left will be full blast as right side has no power butu can feel a faint coolness. if that makes any sense....then could days later the sides were reversed, side that was full boas is not faint, just really annoying. acura told be its a part that costs $268.00????

My 1999 TL blower stopped working. The resistor is below the glove box, against the firewall, and is held in by two screws. Takes 10 minutes to replace.
