2003 Pontiac Grand Am gt. the blower motor stopped working on settings 1-4 only 5 worked. Then 5 went out a couple months later. I replaced the 30amp fuse in the engine compartment and it worked again for another couple months. Now it pops the fuse instantly so I replaced the resistor. Still keeps blowing the fuse and doesn't work on any fan speed. Any suggestions?
You'll need to replace the switch and the blower motor. If you just put on a blower motor it will probably work on five. Its more difficult pulling dash apart then it is replacing the switch, but that's what's going on.
If a fuse isn't burnt through it works as good as a new one, so keep the old for possible future use.
Hi
the problem lies with the selector switch.there is some short circuiting taking place inside the switch.so please replace the selector switch.
