Hello and welcome. this vehicle uses two electric motors called door actautors. these actuators move the passenger and drivers temp doors to ajust temps from hot to cold, and cold to hot. the actuator for the passenger side is causing your problem. you will need to replace the passenger side actuator. just a note, do not plug in the actuator until it has been installed.

ubder the passenger side of dash you will see a plastic cover called a insulator. remove this cover, after that you will need to remove the glove box, then you will be able to gain access to the actuator.

  • Release the insulator retainers from the lower I/P trim pad. Lower the insulator.
  • Rotate the courtesy lamp socket counterclockwise. Remove socket from the insulator.
  • Remove the insulator.

  • Remove the screws from the instrument panel (I/P) compartment.
  • Open the I/P compartment.
  • Depress the side stops located on the sides of the I/P compartment.
  • Carefully remove the I/P compartment.

  • Disconnect the electrical connector from the right air temperature actuator.
  • Remove the screws retaining the right air temperature actuator (2).
  • Remove the right air temperature actuator from the HVAC module assembly.
  • Position the right air temperature actuator (2). Align the slots in the electric actuator driver to the flats on the shaft.
  • Align the locating hole to the alignment pin on the HVAC module case.
  • Slide the actuator on the shaft. The actuator driver should seat completely onto the shaft and the mounting holes should be flush with the mounting screws on the HVAC module case.

    1995 Lesabre blows hot on drivers side, cold on passenger side

    THIS IS A GUESS. Both sides probabley have "mix" dampers that regulate temp by mixing hot and cold air to make you comfortable. Passenger side must not work properly, stepper motor? Dirty actuator? Temp sensor on passenger not working? Don't honestly know but I'm not sure a do it yourselfer could figure it out. Sounds complicated.

    Driver's side air blowing warm, won't change

    Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

    Driver side vent is blowing out hot air,passenger side is blows out cool air

    Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.
