My 2003 Honda Accord LX 4-dr 4cyl blower fan quit. I cannot find a fuse labeled for that either inside or under the hood. At Advance Auto Parts they said the trouble is a relay but they could not help to identify it. I had the compressor replaced a few months ago with an after-market.
I would test the blower if I know where is was and what kind of cable connector is on it. The compressor seems to be ok since it comes on for a few seconds each time, but the fan does not come on at all. (I know, if the fan does not run, neither will be compressor to protect it) If it is the ballast resistor, where is that located? The parts store wants almost $100 for that part. WOW!

I have never seen a fuse panel with such insane labeling as this car has on both panels. Guess it was labeled for just techs at Honda.
Any ideas?

 

Not sure which fuse is for the blower motor. Maybe the owner's manual will have that information.

If you have a volt meter, unplug the two pin connector that goes to the fan (#2) in pic. The location is under the glove-box. Turn the fan on and see if you have voltage across the pins that lead to the blower motor.
