Frist I had fitted a new compressor ( it didn't give enough pressure to the system and was making funny noises all past summer).
Then the guys who replaced the compressor said the dryer was blocked from dirt, so it needed replacement aswell. Have not been able to find a suitable dryer replacement for my pre-1993 system, so this guys have made a real good job and fitted a Ford model and modified all tubes to fit the thing.
Now the system jumps in and cools firmly but after a while the auto-fan switches on to bring down the temperature. It also brings down system pressure. Then switches off again after 10 mins. Then kicks in again and won't stop. So it brings the system pressure down too low and it won't cool enuogh.
They're thinking of a bad temperature sensor of relay somewhere. According to 1991 wiring diagram there's a AC relay in possition E in the relay box. Where are the other relays in my AC system? I have one of those pre-1992 VEM with off button on the right.
Any ideas at all ?
