Thread: Freezing my arse off...

could be your ignition switch....

Do you have any other electrical issues? If it were the ignition switch, you would probably see some issues with the Drivers Information Center, the radio and possibly other accessories. I think that perhaps you probably have just a bad blower resistor module from the sound of it.

Could be more than one issue as well. #5 can go out all by itself and you still have 1-4 functionality if the resistor goes bad. Ignition switch would cause and issue with 1-4 and other accessories.

I would lean more towards a bad resistor. I would start by changing that and see where that takes you.

It's a bad resistor. Had the problem in my old 97 GT and currently have it in my brothers 99 Grand Am. I had it replaced at the dealer before but from what I have heard, it's not very hard to do.

Also, in response to your digital climate swap, can it be done? yes. is it worth it? no. There is a tremendous amount of cutting and splicing of wires in order to get it to work. The Digital Clime Control is controlled by a single connector in the back of the unit. The knob units are wired individually to each switch.

For the most part, replacing the resistor is kind easy. However, most of your time will be spent getting two bolts that hold the resistor in place loose enough to get the resistor out. I spent $40 in craftsman tools to get the one I needed to just turn those blasted bolts a few turns.

Man, that Bonneville blower motor resistor is vastly different than the one for the GP. But the seller is Ed Morad and he is a GREAT guy and if you contact him for anything he will get you hooked up. I dont know about the dual climate control, I already have it so Im not sure what would be required to switch to that.

I would need to see that back of that unit. Also, I haven't had to look at the back of those units in years. Do you currently have a 3 knob control in your car or a 2 knob with dual climate?

The other thing you could do is, I've seen Reptile post up different wiring diagrams. If he works at a dealership or has access, you might want to see if he can find the charts for your GP and an Impala unit to see if they require the same wires.

I'd try getting the wiring diagrams to see if it is the same. I would imagine that the wires going to the knobs would be similar. Not sure about the dual climate controls.

Anywho, like I said, start with the wiring diagrams
