What's up with that?

Does anyone have any idea why my a/c compressor would still kick on with my heater? I have factory a/c and am pretty sure this is incorrect. Any help would be appreciated.

Re: What's up with that?

Depends on what output you have it on. It's common for a/c's to turn on if you turn it to defrost. If it turns on for every selection though, something might be wired wrong.

Re: What's up with that?

Well I checked it out today and no luck. If this is indeed a wiring snafu, does anyone know which wires to check. I'm good with trouble shooting but a little direction would help a bunch. Has anyone had this problem before? I know I cant be the first

Yea, I already thought of that. That's actually how i have it running now! I was hoping for more of a "permanent" fix, but not opposed to "makin it happen" either Gotta love Field Expedience!
