2002 Suburban, a/c chirping noise
Hi, first post here, because I've never had a problem I couldn't figure out till now.
2002 Suburban, about 140k miles. This past Wednesday drove up to Baltimore for the U2 concert (awesome show) and when got there , I had to make a u turn into a parking lot. After the turn, noise coming from a/c area. When turned off a/c, noise went away. When turned it back on, a/c began to make a chirping noise, no noise for a few seconds, then chirping, then silence, and so on. But the a/c continued to work, no problem, and cold as always.
Drove home with a/c home, notice no issues. But the small chirping noise continued when parked and running a/c. And I have notices it gets worse when in parking and I rev up the motor.
I can make a recording and post if it would help.
I've read that this could be due to some sort of belt, or a code that needs to be updated on the computer it carriers, but what do I know.
Also own an 1983 Mercedes 240D, so if you have any MB questions ask away, much more knowledgeable abut my Benz than Chevy.
Thanks in advance for your help!!!
I am praying this is not a costly fix!!

Welcome to the forum,
If you have not replaced the serpentine belt I would try that first, the next likely culprit could be the compressor clutch, could be dirty or worn...
