No fan for the heater - 1996 Pontiac Grand Am

Usually bad blower motor resister mounts into the heater box under hood.

Remove the Glove Box assembly. The heater fan and the heater fan resistor are behind the glove box. It is on my 90 4-cylinder Camry.

see this and fix it. God bless you

Remove the passenger footwell lower trim panel underneath the glove box.

2 Open the glove box and remove the screw holding the footwell air vent duct. Pull off the hose and remove the duct. Close the glove box.

3 Disconnect the heater fan electrical connector. Remove the three bolts retaining the heater fan and remove the fan.

4 Disconnect the heater fan resistor electrical connector, and remove the resistor.

5 Install the new heater fan resistor by reversing the above steps.

It can be issue with relay or wiring of the fan causing the problem.

2008 nissan versa mice nest in heater fan box. how do i remove heater fan blower?

your fan speed regulator located on your heater core box is bad if its just one or some of the speeds. if the fan does not work at all its either a bad connection to your fan speed regulator or the fan motor has quit. out

You need to replace the heater/AC blower motor the motor shaft bearing is defective..

Have you checked the earth? You may find current is going to earth via the fans. Find the earth for the heater and make sure it is earthing really well. Hope this helps.

Hi: Sounds like a possible heater resistor problem. First check to see if heater fan working, unplug heater under hood and put 12 volts to it from the battery with a wire (single black wire running to back of fan). If works then problem probably the resistor which is located on the fan housing under the hood to the right of the fan. The resistor has wires to it running from the heater fan, 2 - 7mm screws holding resistor in place, check resistor to see if any of the 3 elements are melted off, if so replace. Note: Rear window defrost has nothing to do with heater fan. Hope this helps...

You most likly need to replace the fan or possibly the fuse for the fan blew.
