ac compressor kicks on when I turn on the heat

[Silversurfer Gio]

Well, my 04 gp, for the last few months I noticed that when i turn my heat on the ac compressor engages. Im just wondering what the problem might be, Ive seen this once before on one of my friends cars and it was the computer, but I just want to be sure. any help would be greatly appreciated.

I'm curious about this myself. About once a month, I'll look down and notice the AC's on for no good reason.

I've noticed this on occasion as well. I just thought that I'd been accidentally mashing the A/C button instead of the rear defrost, but maybe my car's possessed too.

Do you all have climate control?

A/c turns on with defrost to pull humidity out of the cabin.

With def, floor and def the compressor will run unless the temp is below 32 degrees.

So this is normal? Ok good I was gettin worried for a second. thanks fellas

Yea its "normal" but its a feature a lot of people dislike. Just be glad we can easily turn the compressor off if the climate control decides to turn it off. On other cars it comes on automatically and there is no way to shut it off from inside. I know guys who disconnect the compressor in the winter time to keep it from happening.
