  Blower Motor Stopped Working! Need Help!« » 11:27 PM 7/8/2007 Reply  Edit

I have a 2002 Honda Civic with about 80K. We have had not one problem with this car until last Friday. I was going to lunch, it was a really hot day, I go to turn on the AC and there was nothing blowing out of the dash. I tried the heat, that also didn't work. I am baffled as to what this could be. I looked at all of the following:
1. Voltage to blower (it has 12 volts with the key on and switch on)
2. Jumped blower to battery (It worked)
3. Checked underhood relay & dash fuse (everything looked good)
4. Checked the ohms in the Blower Power Transistor (I think that it was ok??? I compared the ohms to a new part at the dealer & it was exactly the same)

I have no clue what else to try. I would like to fix it myself if all possible but I have a newborn & I really hate driving in 95 degree weather with him in the car. Any thoughts or suggestions would be greatly appreciated! Thanks for your time!

I wasn't sure how to check it. I did pull that assembly out of the dash and looked at all of the wires and everthing looked ok....

Also, I had the blower hooked up but out of the dash and when I turn the ignition on the blower spun for a quick second. It also did this with the switch in the off position. There is a constant voltage though of 12 to the blower with the key on & the fan switch in the off position.

i'm not sure but the switch should have a 12v out telling the blower to turn on with the key on.. i'm not sure which wire it is.. you can't really go by looking at the switch cause it might look ok but it could be a bad wire..

Thank you so much Jivi!!! I tested the ohms first thing this morning and it didn't even register (I believe open...) I am going to solder a resistor on this morning and see if it works! Thanks again for your help! I couldn't have done it without you. My wife also wants me to thank you, for saving us so much money.

when you were having this problem did the compressor still turn on?

I just want to say thanks, I am new to the forum, I registered because this thread simply fixed my issue.

I did the thing yesterday and IT WORKED FLAWLESSLY!!

did cost me only 59 cents to fix it for five 1ohm 1/4 watt resistors, they were selling them in pack of five.

thanks a million jivi

Great tips!
I have one more obscure possibility in case someone else has this problem.
And I speak from experience.
After replacing the resistor on my 93 del sol, I removed the blower motor and tested it with a battery charger. The motor was still good. Next I tore out just about the entire dash to get access to the actual switch assembly. (Long, involved and requiring the skills of a contortionist) Once I had the switch in my hand I tried rotating the post to the various speed settings. When it was still installed in the dash, I would turn the knob but there was faint resistance between settings. Now with the switch assembly in hand, it would click between positions.
The answer...
The black plastic switch knob was cracked and wasn't able to turn the metal post that it was assembled on.

The car had come back from having bodywork performed and my guess is the less than reputable guy working on my car created the issue somehow. It was a cheap fix, but a long and involved diagnosis.
