Heat that comes out the driver side is cold compared to the heat that will come out of the passanger side
SOURCE: I am a owner of a 2000 cadillac catera and my
THIS PROBLEM OF NO HEAT IS CAUSED BY A FAILED AC/HEATER AIR TEMPERATURE CONTROL BLEND DOOR OR BY THE MOTORIZED ACTUATOR THAT MOVES THAT DOOR, THESE ARE THE ONLY PARTS THAT CAN CAUSE THIS PROBLEM, WHICH IS COMMON IN LATE MODEL CARS SINCE THE 90'S, THE REAL PROBLEM IS THAT THE DASH MUST BE REMOVED FROM THE CAR TO ACCESS THESE PARTS.
Testimonial: "You are awesome, thank you so much!!"
SOURCE: Hot air blowing out on passanger side only, 03 Cadillac CTS
junk it its not worth it one of the sensors that open and shut the door are bad
SOURCE: Passanger side heater blows cold while driver side is hot
U will need to replace the pass side air temp control blend door acuator motor.
SOURCE: Heater blows hot air on driver side but cold on Passanger side ?
either the heater rad is chocked up and its not hot all over,or its a flap opening problem
SOURCE: heating problem driver side blowing hot air passanger side blcold
its likley to be the pipe has been riped off or fell off or its the flaps on the heater box its self not opening,,,have a look under the dash to fine any pipes that are off the heater box,,
anyhow, who cears if the passanger gets cold,,, its the driver who needs to keep warm!!!!
unless its the other half? or worse still its the mother in law!!!! ho ho ho!
