Hi all
i have a strange problem here with my usr s6 aan 1995
the fan is working
problem - a/c disengaging sporadicly. normally it works for like 5 seconds and goes off.burnt fuses, hot wires (a/c wires, almost melted them ) and when a/c is on, it feels heavy on the engine. huge rpm drop even if i accelerate the car...
i changed the relay on the engine bay, but it is the same.
Tests:
upon further verification, i have error 20.3 (20.3 A/C compressor voltage not OK - sporadic)on climatronic (doing the recicle + up button) and checking status.
then i checked the actual voltage at the compressor clutch, and disengaged, it had 13.8 v. engaged, it drops to 9.5 ~10.1
not the actual alternator ,ok? at the batery, i am seeing 13.5 v
the a/c wires are getting very hot,i blew 4 30a fuse (they melted during the tests).
The wires get hot from the fuse box all the way to the compressor clutch.
what´s failing?Any idea?
thanks a lot
