    At least it's strange to me. I've had the truck since October 2017, and I've always had this issue with the AC in that regardless if I have the AC switch pushed on or off, when I turn the on blower fan the compressor turns on. The only way to run the fan and not have the compressor turn on is to pull the compressor fuse.

    I replaced the relay and that didn't seem to do anything.

    Has anyone heard of or seen anything like this?

    Do you have defrost on as well? The AC compressor will kick in to help dry out the air, without actually blowing cold air.

    No, not running the defrost. This is just turning on the fan w/o the AC button switched on.

    The only thing I can think of is that a previous owner installed an after market stereo and wired something incorrectly. I have no idea what they would tap into to cause this issue.
