2003 Malibu blows hot air from vents no matter where temp is set and on ac also

Blend door is not working. Could be the door is stuck, wiring issue, bad actuator or control panel issue. In your car, the actuator is not too hard to access. Follow the instructions to access the actuator. Check the connection. Before removing the actuator, turn the key on and change the temp setting. If you hear clicking from the actuator, it has probably stripped its gears. If not, remove the actuator and check to see if you can rotate the door by hand. If not, you will need to remove the duct to see why the door is jammed. If the door rotates by hand, plug the connector back into the actuator, turn the key on again, and change the temp setting while watching the gear on the actuator to verify operation. If the actuator doesn't turn the gear, the problem is with the actuator or the controller. Remove the connector again and probe the connector with a voltmeter. Turn the key on again and probe the terminal of the light blue wire. There should be voltage there when you change the temp setting. If not, the problem is with the control panel. If there is voltage of a few volts or more, the problem is the actuator.

Removal & Installation

Remove the fuse labeled HVAC CTRL (BATT).
Remove the left closeout panel.
Remove the knee bolster.
Remove the air temperature actuator screws.

3G Mitsubishi Eclipse Climate Control Light Bulb Replacement

The control panel for the heater and A/C must be removed. Suggest you get Chilton's manual from the library. It will take you through step by step with pictures. To summarize: 1) Remove trim panel covering radio and heater controls. 2) Remove radio. 3) Disconnect the two heater control cables from the control panel. The trick to removing the cables is to compress the "claw" spring holding the cable by pressing a screwdriver from the underside of the control panel to release each cable.4) Remove control panel. Take to a workbench. From the backside of the control panel at the top, notice two large holes through which you can access the V2 Toshiba bulb holders. Turn them a quarter turn to remove them and the bulbs. The bulb is a common #74 bulb.

You need to remove the console upper panel, and the center inst panel finish. Remove the screw under the middle knob, and the 4 screws behind the upper compartment door. Disengage the 4 clips and the 4 claws. Pull it straight out. Release the 2 claws that holds the heater control to the inst panel. You should now be able to access the bulbs. This should help you; repost if you have any problems.
