I am in need of a wiring diagram for a 1991 Acura Integra LS. I have an issue going on with the heat in my car. I've tested all the wires that go to the blower motor and resistor switch (new-ish) resistor switch installed. I pulled the blower motor out and tested it and it ran fine. It's brand new. Now I am stuck on what to do, what else can I test? I only have 2 more weeks to get this fixed before I have to drive the car, and I live in Southern Wisconsin so it will suck.

I've also checked fuses and all are fine. Could it be the speed control switch? Because when I 1st got the car I took that switch out and it also has the a/c button in the middle and I found the power wires and I used that switch for my CD player power, because I hve no a/c anymore. Could I have fried the switch when I did that?

Funnily enough it was always THAT switch that failed on Hondas of that generation, always look to the switch first especially when you appear to have eliminated the other factors, rheostat and fan motor but also check your fuses. Radio acc fuse in driver's fusebox, permanent is a 7.5 amp fuse, also runs the clock, engine bay fuse box.

Thanks man.

I tested the switch and It sent 12 volts on all four of the speeds, But I ran two new wires and hooked up a switch and my heat works fine. So I guess I'm going to just leave it like that, because after winter is over I will probably be taking out all of the heat.
