Honda Car Forum

Just last week I noticed my levels 1 and 2 don't work with my a/c and heat in my 2002 Honda Accord. Levels 3 and 4 work fine. If I have the a/c on level 1 or 2, the a/c indicator light does come on. So I know I have power to it. But no air comes out of the vent unless I but the level to 3 or 4. I have a knob that selects my levels, not buttons. Would it be a bad relay? Bad fan switch? Bad knob? I would really appreciate if anyone had any ideas. Thanks a lot!

I am no mechanic but I have worked on many cars and found similar problems sometimes it is just the switch isnt gettin a good connection. But in most cases its just the Fan its self dying slowly

You probably have a bad blower motor resister. If memory serves me correctly. It is under the dashboard behind the glove box near the fan motor. Look for a rectangler shaped block with a plug going to it. It is usually held in the duct by 2 screws. If you find it and take it out, it looks like several springs of different sizes. One or two of them will be burned and broken kinda like a bad light bulb filiment. If not under the dash, look under the hood in the vicinity of the fan motor [ usually on passenger side]

There is a "dropping resistor" someshere inside the heater box (near the blower cage), -- it has two portions burned out! If you have a manual, it will tell you where it is, -- if not you will have to hunt for it! It is about 1 1/4 x 1 1/2 in size - held on by two screws, and had a plug Or wires on it (probaly 4 to 5 of them!) If you remove it, you will see little coils of wire on on the other side form the( plug). These are the "resistor coils" that drop the voltage to make the fan run slower (the fan cools the coils so they don't burn out)!

It is probably just a faulty switchhope that helps

the blower motor has gone out.its located right under the dash on the passenger side.my civic did the same thingrweplace it..it costs about 50 bucks (give or take)

Its the blower motor resistor. Its a Card with about 4 different resistant paths controling amps to the blower motor depending on which speed you select. Very common.
