New here hoping someone can help. AC started dying a few weeks ago when it would work fine in the morning when cooler but at noon or going home when warmer it would work a few minutes and quit. Warmer it got worse it was and compressor was clicking a lot like it was trying to engage. Had the system checked and everything checked out, good levels and pressure with no leaks. Then it would not work mornings until I drove for 10-15 minutes and would work the rest of the day until the last couple days when it would not kick in at all. One thing I noticed is the outside temp on the dash had always read a little low, but since this started it has been farther off. Today was close to 90 out and it never read over 17. Could that sensor be telling the system it is too cold out and it doesn't need the AC? Looks like a new compressor may be in my future since the gap measures ok for what I have read here. Thanks for any input.
