SERVICES PERFORMED: I have always kept the AC system serviced, & @ 123k & 127k have had the AC system checked with dye, black light and "sniffer leak detector." It showed "seeping at the compressor and evaporator." Car has been carefully maintained since brand new (father owned up to 40k miles); although I note that at 30.5k miles the evaporator core was "blown" & replaced (surprising) by the Cadillac garage. In the nearly 100k miles since then, I've done nothing to AC other than had it checked, periodically recharged & had the compressor relay replaced (31k & 120k).
Answer: If the amount of refrigerant in the system is correct, then we suspect the fan controller module is malfunctioning.
have the same problem?
