Anyone else have this issue ? The A/C compressor on my truck is cycling no matter what setting the dial is on, floor heat, out the dash vents it does'nt matter. Any body have this problem and whats the fix ???

Looks like a PCM problem, what ya think?

My truck does the same thing, didn't find out till i went drag racing and i kept dripping water out of the ac houseing. Had to pull the fuse to stop it from running. I haven't looked into it all since then, just put the fuse back in so it worked.
 
Both my 01's do it. Always wondered if it was normal. Starting to look like it is.
 
mine does it too. probably for defrost reasons. because for some reason dodge didn't give us a seperate a/c button, they probably just made it so the a/c runs all the time to provide optimum defrost.
 
My 99' only does on defrost and the two air positions, not the others.
