Dealer ran computer and determined AC compressor pressure sensor needed to be replaced. After replacing pressure sensor, problem was not fixed. Kept vehicle for nearly 2 weeks and determined that a new compressor was needed because they could not get the one in the vehicle to work. Was told they checked the pressure lines for leaks, the electrical lines for continuity, and all sensors and relays which all checked out to be ok. Replaced compressor for $1,700 and returned vehicle to me. 3 days later, the same problem reoccurred. More details in next complaint.
