Getting desperate...my AC has been blowing hot, checked 134A fill level ok, compressor turns, no condensation on low side lines tho. Hadn't noticed that untill after I changed the DCCV. Ran the diagnostic mode and came up with 1342 code...replace DATC. Is there anything else I should check before buying a new control unit? Didnt see it listed on Rock auto. Anyone know a good source beside the stealership?
