Having a minor intermittent A/C issue on my 03 Suburban 1500 5.3
Always at idle to start the problem, then at low speed until it goes away, the AC will sometimes start blowing warm, humid air in between cycles of cooler conditioned air.
The cabin gets noticeably humid, and I can feel when the compressor tries to kick in, at the same time, the vehicle surges forward.
This happens intermittently at idle, sometimes at startup, sometimes in gear with brakes on and when it does do it, it will continue to do it until I get up to speed around 30-40 mph before it starts to cool off again, then it will be O.K until it decides to act up again.
No problems at all at speed
Any ideas?
