I'm Awesome
1995 K2500 Suburban
454 7.4L
with front/rear A/C
I haven't put pressure gauges on the system yet .... Because I suspect electrical at this point.
Here's the 4 weird symptoms encountered so far:
-- Occasionally, the A/C and Recirc buttons do not light up when pushed. No matter how many times I push them. The compressor engages and A/C works, but button doesn't light all the time.
-- Also, occasionally, the a/c stops blowing cold air, like the compressor shuts off. After a short while, cold air again.... with no regard to button light.
-- Occasionally, when on Max setting or with Recirc on, you can hear/feel the fan speed vary from High to Max. .... Intermittently.
-- Sometimes, the clutch will engage/disengage repeatedly. I can shut off the engine, restart, and all is good.... except for the above mentioned issues. .... which only occur intermittently.
Looking for the best place to start troubleshooting.
I've read here that the door motors go bad & also come loose from the doors.
I was just wondering if these symptoms could be due to door/motor issues, dash button/switch issues or charge/pressure issues. ... or maybe all three?
My first plan is to hook my gauges up to check pressures.
Any tips on where to look for solutions?
