Re: 1998 Blazer revs at Idle
Thanks for help and advice. The problem is the AC. Not sure yet what is wrong with AC, could be low coolant, I suppose. Determined it was the AC by pulling the 10 amp fuse for the AC. Problem immediately went away and didn't return again until fuse was plugged back in. The air setting was on defrost and that was causing the AC to try to engage.
Visually, it looks like the AC clutch is engaging every few seconds and then kicking out again. Little to no cool air is coming out. Any thoughts on the AC? Imagine I will need to have that serviced, but it would be good to know if you think it is coolant, if they suggest something more drastic with the AC.
Blazer is back at college again, so I won't see it for a while. Thanks again.
