Ok I've searched. Looked at various other threads.
Cooling fan does not come on with A/C on or temperature.
Can force fan on high with jumpers and by removing the Temp Sensor connector on the heater hose.
The fan has 3 pins. I know one is ground and I assume one is high and one is low power in. When hot wired, I only get one speed, high. The center pin (low speed?) does not respond. I'm guessing that this means the fan is dead on low speed.
Is low speed the speed the fan comes on for the A/C and high comes on if it gets too hot and needs to cool it down? If so then I guess I found my problem.
Changed IRCM out. No differences.
Now the pusher fan has been dead. We are not discussing that here. It is frozen and I have a replacement. But I need to know what I am looking for on the puller fan.
