I am having a peculiar problem with my Pajero's AC. While driving, the AC switch suddenly starts flashing on and off, and the compressor stops working. I then have to turn off the engine, restart the car and it immediately starts working for some time. I have been facing this problem over the past few months with the frequency increasing recently. I have also noticed that with continued hard acceleration the AC doesn't turn off that often. It tends to happen more while the car is cruising. One mechanic told me that the AC clutch or something is slipping but I didn't quite understand what he meant.
Any advise or suggestions?
