Does anyone know how to check the module in the dash? ive already checked the fuse, and the blower motor itself.... Both are fine. After a while with the windows up it starts to get warm inside, but nothing happens when you flip the switch on for the fan. therefore I have no forced air, and you can't hear the fan come on... Any suggestions on what it might be?

 

I'd pull out the module and take a look at all the connections at the back. Also follow the wiring to make sure it's looking good.

I had problems with mine and all the connections at the back of it were all sorts of melted.

 

so is it just wires back there, or are there any rods, plastic connectors or anything else?

 

All of the above. Plus vacuum lines.

How about testing for voltage at the blower motor?

 

I haven't tested voltage on it, I just pulled it and hooked it straight to a battery and it turn on. What should the voltage be?

 

About battery voltage-12 or better.
