2001 Chev Impala-signal, dash, AC/Heater control Sign In


My wife has a 2001 Impala with numerous electrical problems. I have no idea were to start. First, I have checked all the fuses and they seem to be ok. Here goes.

1) First the dash lights quit working. They came on once in the last six months. Then went out again.

2) After that the turn signals and flashers quit. They work when they want to. So it is a hit or miss if and when they will work.

3) Then the AC/Heater fan control quit working. It did come on a few weeks ago. But was on for a few miles.

I am not sure if they are related or not. Any help would greatly appreciated.

I think I have solved the turn signal problem. I removed the dash and the emergency hazzard switch. When I played with the connection, the turn signals started working again. So waiting on the emergency hazzard switch, to see if it works.

The AC switch is not working. I am leaning towards the fan motor resistor. Now if I could only fine the thing. I was told it was behind the glove box. Not sure what I am looking for. If I do find it, how do I tell if it needs a new one?

When you say the AC switch do you mean the blower fan?
If so the resistor is behind the glove box on the underside of heater plenum housing beside the blower motor. Follow the two wires from the blower motor to the next connector (about 6 or 8 inches away) and that’s the high-speed relay/resistor assembly. GM has had a few of these things fail. LOL
Use a test light to test for switched powers at the resistor; it’s a pretty basic blower motor circuit. Here’s a wiring diagram that should help.
