Having problems with your Oldsmobile Regency ?
1997 olds regency a/c malfunction. when a/c is switched on, only hot air comes out from the passenger side (only) dash vents, all other vents have cold air. the manual override switch for the passenger air temp does not override it , the rotary switch on the pass. door armrest was set to hot, but i turned it back to cold setting, but still no cold air from pass. side dash vents ............about 10 days ago i noticed the outdoor temperature readout on the dash would flash
It sounds like a defective temp door actuator. It is behind the glovebox. You should be able to unhook the rod from it and move it manually. Run the engine with the glove box out and move the temp control to see if the actuators move.
