Question about 2000 Pontiac Sunfire

Heat/defrost motor quit

I would like to defrost my windows, it's a need now, not a want, to have my fan working.
it started working/quitting intermittently over the summer after our ac hose blew off in the engine due to a cracked rad seal and now it seems to sort of come on when we slam the door or if we go over a bump. but when it does start working, you can hear the motor or the fan slowly winding down and then all you hear is a knocking clicking noise until it stops completely....does that sound to you like the bearings in the motor (is that same as the motor resistor) or could it be an electrical short....?

I have a 99 sunfire and if you look under the dash on the passenger side, there is a circle shaped cover over the fan. on mine the problem was that the wires behind it came loose. jiggling them in certain ways would make it come on again full strength. i simply taped the wires into the right position so they would connect, but i'm sure there's a better more permanant solution if you have the right tools to get the cover all the way off and look at the wires. apparantly this is a common problem among sunfires.

Yes the motor has most likely failed, I would replace that and the motor speed control.

Could be the blower motor, or the resistor, or a bad connection in the harness. Someone would need to check for power and ground at the motor first.

Defrost fan quit working.

Check it with a test light or Multimeter for power to blower motor first, with switch on high. If no power to motor, problem is elsewhere. Here's a link that will help you. Click on the pictures to expand.

Subaru Loyale 1994 Heating fan quit working

one of two solutions:

The contacts on your fan switch are bad, or you striped the knob and it won't turn the switch on, or the big bad one...your fan motor has decided it needs a vacation.

Hope this helps you, and I hope it's just the knob is's the lesor of two evils
