This answer was rated:

hey Doug this car has become a nightmare now my air conditioning compressor seems to be cutting off while I'm driving and the only way to get it back on is to turn the car off then back on. the compressor stays on for about 3 minutes then shuts off

Hi,

That's not a good thing.... are you seeing the AC light flash at all?
When it runs for 3 minutes, does the low side pipe (the larger diameter aluminum pipe) get cold during those 3 minutes?

Customer: replied 1 year ago.
its cold and the fans turn off also

Thanks, ***** ***** a good sign of possibly just a low charge condition.

Do you have access to AC pressure gauges?

Customer: replied 1 year ago.
I thought that is what it was so he just checked it and it is good

What are your high side and low side pressures while it is running?

Customer: replied 1 year ago.
Not sure just left the guy

Well the concern here is if the system is shutting down intentionally or not.

When the AC cuts off, do the outside fans stop too?

Customer: replied 1 year ago.
really weird I just took it for a drive and now it's staying on when I've been driving

Hmm.
If you let it idle for a bit?

If it continues to work OK and you want to close this for now just let me know.

Customer: replied 1 year ago.
I'll just close it right now. We keep in touch all the time anyway

No problem; if it returns we can pick back up.

hey Doug my AC compressor keeps cutting out after like a minute I just don't know what the hell to do? 2004 Mitsubishi Endeavor

If it is turning back on after 10-60 seconds that is OK... the compressor should cut off after anywhere from 10 seconds and up (depends on charge amount, temperature outside, etc).

If it is not turning back on, then we would suspect a thermistor issue (in the evap box), pressure sensor issue, or even worn out clutch magnet.
We really would want to read the two sensor values on the scan tool to see what they are seeing, but you could also check for power at the clutch when it cuts out... if there is power there, then the magnet is bad.

I also notice my gauge lights for my rpm miles per hour and temperature go out after about three minutes just now the compressor just kick back in and it's been blowing cold air for about 3 minutes nowsomething is wrong
Customer: replied 1 year ago.
the gauges just went back on
Customer: replied 1 year ago.
could this be because of the flooding in my floorboard I fix that issue with the pipe you told me to order now she just kicked off

Yeah, that sounds pretty unusual. I would check all your connectors particularly around the drivers kick panel ahead of the door etc for signs of corrosion or moisture in the wiring.

hey Doug can you provide me with a schematic for the AC system please

Sure, I'll need a few minutes.
