I have a 98 Ram 1500 w/5.2l..When I run the A/C, it will blow out cold then suddenly it blow out warm..then afterwhile cold again..It happens when I'm at a stand still or moving at 65mph or faster..A co-worker told me it could be my A/C pressure cut/out switch or clutch cycling switch..Any ideas?

 

Have you confirmed that the compressor is turning off when it blows warm? I'm thinking you have a vacuum leak. Check out this thread https://dodgeforum.com/forum/2nd-gen...ild-vents.html

 

Compressor is running & it doesn't look like there are no leaks..hoses look clean-no oil residue from freon..When I looked up the cut off switch & cycling switch on Autozone.com, both look the same but are different in price..13.99 vs 34.99..not sure what they both do?
