This is for my mother. She has a 97 Civic with two hundred something thousand miles and the A/C is dead. It first started with the two lowest fan speeds DOA and now the whole system seems DOA. I need to find a schematic for the A/C system since there are so many sensors in the system. Honda systems are much more complicated than domestic ones. My father and I intend to fix it since they do cost a great deal to fix. I will greatly appreciate any help I can get, and so does my father since he has to live with her through a south GA summer. Hot and humid is not a new weight loss plan, though I could probably market it and make millions.

 

well, since I don't know anything about a 97 CIVIC ... mainly because this is the 88-91 EF Forum, and you posted in the wrong place ... I can't answer

 

Well it happened to my friens accord a couple days ago here in Ga and it turned out to be the blower motor.

 

Thanks, so were can I post? I couldn't find an area for 97 civics and this was the closest thing.

 

It isn't the blower moter because the fan still works on the two highest speeds, though it should be replaced. At around a cost of 150ish, plus there is the whole remove the dash thing. I just fixed my Subaru's blower motor, a melted wire problem, no need to remove the dash!! I wish all cars were like that! Thanks for the relpy!!

We replaced the blower in the accord in about 15 minutes without removing the dash. I also did one in a crx without removing it either. So what exactly does it do?

 

My father can't seem to figure that out due to the complicated sensors involved. He has gassed it with old school equipment, but now worries that he has put too much gas in. We really need a schematic for it. Mom moved his book for the car and now they can't find it. She does things like that.

 

Did he use r12 or r134? They usually take about 1 1/2 pounds. So the blower motor works on 3&4 but doesn't blow cold. Is the compressor turning on?
