alright, so i have bought a 94 acura integra with a b20 swap in her. only thing i have came across to be wrong is the heat/ac..im not getting any air out of my vents. i took the blower motor out and jumped it to a battery, it was. i took the plug that plugs into the top of the blower and checked it for power, it got power going through the 1234 speeds, but only when i had the ac pressed on? uhmm i havent really got to spend a lot of time on her besides last night and thats what i have figured out so far. if anyone has came across the same problem or something similar and can point me in the right direction that would be great! thanks for taking your time to read this.

 

So did the blower motor work?

The "plug that plugs into the top of the blower" is the blower resistor, there should be no power at that plug.
The blue lead should have a ground when speed 1 is on,
Blue/white should have a ground when speed 2 is on.
Blue/yellow should be a ground when speed 3 is on,
Blue/black should be a ground when speed 4 is on, you should also have a ground at the blue/black at the blower plug when speed 4 is on

The above tests need to be done with both the blower resitor plug and blower motor plugs unplugged and ign. switch off.

Turn ign. switch on and test for power on the blue/white lead at the blower motor plug, [unplugged from the blower motor. 94

 

yeah, the motor worked when i jumped it to a battery. so im really kinda hoping its just the resistor.

 

Have you tested for power on the blue/white yet?94

 

so, i switched out the blower motor resistor, and that didnt do anything. but the one that i did take out was bad lol. im hopping that it could be just the switch's??
