I had the same problem and it ended up that the windshield was leaking on the fuse box. After sealing the leak and drying out the box everything went back to normal.

Your main ignition switch relay has failed in the closed position. You will find a main relay in the engine bay that provides the ignition circuits. It may be identified in the handbook. If you pull it out, all these items should die. If you replace the relay you should be sorted. It may be about £25 though.

Try banging on bottom of blower motor with your hand with switch in high position and key in the on position. If no bower motor action happens, check that fuse/relay is operational. If ok, suspect failure in heater motor or heater motor resistor

Heater fan not working on my 2003 cavalier


From your symptoms I would suggest, inspect the Climate Control and the Blower Motor Resister. Locate and remove the resister and test. You are looking for power at the plug (going to the resister). One wire will always be hot (with the ignition key on). The other four wires are ground wires that through the resister, changes the blowers speed. Connect a test-light to 12volts positive, test that the test-light is working, and then start testing for ground. Unplug the resister and test at the plug. With the ignition key on, test each wire. Each wire should light up your test-light depending on the position of the speed control knob. If it passes then plug the resister back in and probe at the blower motor. The blower motor needs both ground and power to run. Find out which is missing and write back. Good luck.

I turn on heater or air and the controls don't work. no air is coming out at all. the back only works on high.


Sounds like you may have a bad blower motor resistor/module or blower motor. It is located under the drivers side of the dash near the blower motor.

You can check out this how to tip.

http://www.fixya.com/cars/r6571076-blower_motor_not_work

you can also try tapping the bottom of the blower motor with a small hammer or the handle end of a large screwdriver. Tap is the key word. Make sure the key is in the on position and the blower motor speed switch is set to any speed. If it starts to work than the blower motor is bad.

As far as the rear it sounds like you definitely have a bad blower motor resistor. It can be accessed by removing the passenger side rear trim panel. The resistor will have a few wires going to it and will be held to the HVAC unit with two screws.

If you have any more questions just ask. I will be happy to help!

KEY ON ENGINE OFF THE RADIO, A/C BLOWER MOTOR AND


This is normal. It has a timer system cutting Power to all of these with the engine off. It is to limit power from the battery to run these too long, decreasing your voltage capabilities of your battery.
To run the Radio / Power Windows with the Engine Off: turn the Key counterclockwise from Key OFF position to ACC (Accessories) position. Your Radio and Power Windows will operate. Your AC/Blower will not.

Blower motor doesn't blow anymore, This blows


If it blows only on high speed, it is the resister.
If it does not work at all, check fuses first. See owner manual for location.
Then check blower motor by jumping 12 volts from battery to blower motor. Make sure ground is jumped too.

If it works now, it's the control panel. If not, it is the motor.

Heater Blower Motor Switch Resistor(s)
The front heater blower motor switch resistor has the following features:
  • The assembly is located in the engine compartment on the evaporator housing (19850) next to the blower motor assembly (19805).
  • Three resistor elements are mounted on the resistor board to provide four blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
  • An overheating device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F), interrupting the blower motor operation in all speeds except high.
  • The thermal limiter cannot be reset and is not serviceable.
