The car took a beeating from road damage after Hurricane Irma that led to a A/C compressor blow up and 2 wheel bearing failures. With a new compressor, condensor, expansion valve, lines, and relay (at dealer), the temperature intermitently faded away then come back (compressor cycling on-off) a few miles later even on cruise control and an open road at 85-88 degrees. Two years later, it still fades despite numerous inspections. It was not like this before Irma. The dealer thinks "wiring problem". Since nothing else is malfunctioning I doubt it. Since the worst occurances are in bunper-to-bumper traffic with hot exhaust from the car in front, a "too cold" condenser is not likely the casuse of the off cycle. It is as if the system cycles off when the condenser gets too hot (at open road cruising?), but I can't find a service spec for that. Has anyone experienced failure of the temperature sensor on the condenser? Or corruption of the ECM circuit involved?
