Well my AC compressor went yesterday. Im good on knowing what to do and going to replace everything but one thing Im seeing online is due to disimiliar metals at the rear evaporator on these rear air models the write up I seen said 99% of the time you destroy the hard lines under the truck at the rear connectors. Anyone delt with this? Does this mean I have to replace the hard lines going under the truck AND the rear evap? I certainly wouldn't thing flushing all that would be a good idea with a compressor failure.
