If the AC cooling while moving but not when sitting still you have an issue with airflow across the condenser. Check to ensure that the electirc radiator fan is actually coming on when idling and the AC is activated.
I’ll do another test today, but the fan is on lat time I checked. Any way to check how engaged the clutch is? When I spin it after turning off the car is doesn’t spin freely but how can I tell if the clutch is locking up as much as it should?
The clutch is magnetic and you should hear it click when actuvated.
Another thing to look at is your temperature gauge, if your close to overheating the computer will shut the AC compressor off first to save on load.
Outside of checking the air flow and overheating the last thing I would check is the refrigerant charge. Have someone put gauges on and test the pressures.
Thanks!
Hm idk if I hear the clutch engaging but it definitely is. I can hear a loud motor type of sound when it’s engaged. Just don’t know how much it is engaged tho. Is this something that wears out?
It’s never overheating when it happens. Temp is good.
Charged the freon last year with a pump and gauges. Should be good but maybe there’s a leak. If there’s a leak would it work while driving but not while stopped for some time?
