2004 Grand Prix blower motor???? GM Tech. help?
On the way home last night in our 2004 Grand Prix the blower motor for the a/c heater just quit. I have researched it a little on google but I'm still a little confused.
I have read where the control module or resistor will keep them from running but I removed it and have hooked up direct 12 volts from another car battery and it blows full blast.
I checked the connector with a DVM and it goes from about 10v when all the way down up to about 12.5 all the way up. It looks like there is voltage to the fan so I hate to spend $60 plus for the resistor or $50 plus for the fan only to find out its something else.
Any GM techs. mind helping me diagnose further before buying parts? thanks
