I recently bought a 99' Cadillac STS, it has dual climate control in the front and climate control in the back also. When I turn the heat on in the front only the driver side blows out warm air. The passenger side and rear vents blow out cold air. I have turned the passenger side control to off, however you can still feel the cold air. Could this be a sensor problem, or maybe a clogged heater line??
1999 Cadillac STS, heat isn't working on passenger side!?
