I have a 2004 pontiac grand prix, and my air and heater will not work for some reason. Before it was working and then just randomly stopped working and took it to pep boys, said it was the blower motor and I put a new one in and still nothing no air or heat. I tried changing the resistor and still the same. Any help would be greatly appreciated?

If the blower motor isn't working, you need to check to see where power is lost. Start at the motor and work your way back to the switch. There is a relay that could be causing the problem too. It's under the hood. Check that too.

I had this problem and it's actually a pretty simple fix. Behind your radio and blower control module there is a connector (mine is Delphi PA6-GB20GF10) it's your likely culprit and if you remove it and open it up it's probably melted on either of the ground wires. The part is very inexpensive on eBay. Or it can be removed all together and just splice your wires together.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
