A/C Comp Cycles but not turned on?

Any ideas why my A/C compressor cycles on/off when the A/C is not turned on? The compressor and fan kick on/off. I got it to stop by pulling the fuse. This is on a 2003 with the 4 cylinder.

Welcome to the forum.

I'm not too familiar with Trackers but GM vehicles of late may run the compressor when the climate control is set to the recirculation mode or defog mode with the fan on.

Mystery Solved!

Thanks for the info. I went outside and checked it out. Sure enough! With the A/C shut off but with the fan on and the selector in a defrost position, the compressor cycles. I never made the connection.

Thanks!!
