Fan Blower Switch

[tbuckit1]

The A/C Blower switch on my '02 Grand Prix GT only works on high. Any ideas on the fix? Do these have a high speed blower switch?

Any help is appreciated.

Thanks

Do you have manual or digital climate control?

The high speed blower relay is located as part of the blower motor resistor or blower motor control module if digital. So it is either a BMR or A/C module.

Sounds like the blower motor resistor under the passenger dash--$10 at a wreckers. Could also be multifunction switch, but it wasn't in my case. Search the forum for blower motor resistor for tons of info. You'll need a T10? bit to swap it out. Also installing a cabin air filter can help keep water from getting in there and futzing things up again.

You guys have been a great help, gives me a place to start looking! I have manual temp controls, so it should be a little simpler? maybe? Maybe a tad cheaper also.

Thanks again

Yeah it's pretty easy to swap out, although I've had more fun upside down in the passenger seat...
