The clutch cycling switch has popped off of the accumulator several times when the vehicle was parked. I replaced the switch with a new one and it happened again. The pressures on the system are good according to the pressure/temp chart. The system has been changed over to R134a and works great at 85% of the R12 capacity. Did GM make accumulators with different thread sizes, or did I get an accumulator with undersized threads, or is this an indication of another problem with the system?
Where did you purchase the switch from?
