Blower Switch

[kboaz2001]

Our 2003 Grand Prix blower switch only works on #3 and above. Is this a blower switch resistor problem?

Very possible.

The #2 fan speed resistor is probably burned out. The #1 fan speed uses all the resistors in series. If #2 is open #2 and #1 will not work. #3 and higher do not use the lower speeds resistors so they continue to work.

most likely yes. there are other things that can cause this, but the resistor is the most likely cause.

i have an issue on my 1997 pontiac grand prix gt blower switch. the blower only works on number 5, i have replaced the resistor, and the switch all fuses are good. the blower motor is fine. also when it is set to speeds 1-4 the headlights will go out and the rear defroster will not function. i have read that the ignition switch may be the culprit.

anyone have any input on this?

You have a bad ignition switch.

Everything else works in the car, so I am hoping it is just the blower resistor, I would hate to change an ignition switch! Thanks.

Why? Not easy but not difficult either. See link below.

Paulk501,

I agree with Bob (Bnaylor) that you have a bad ignition switch.

kboaz2001,

If you have no other symptoms, the resistor should fix your issue.

thanks guys, ill be ordering one soon
