After disconnecting the battery to do a bit of welding for the header install my vents keep defaulting to defrost. Got hot and cold left and right but cant get it off defrost. I watched the servo do its calibration and noticed it only goes halfway through its range before going full defrost vent. Weak servo maybe? My crappy odbII reader doesn't show any codes. Does it require a high end unit to get to those codes?
