Having problems with your 2001 Pontiac Grand Prix ?
On our 2001 Pontiac Grand Prix, we replaced the blower motor and all settings on the blower control switch work except the first one. The switch has 5 blower settings. Any sugggestions?
Change the switch!
It is probably the switch. The switch has resistors for different speeds. Sometimes when the resistor goes out then that speed won't work. So it is probably the resistors on the 5th level. You can get a new switch at the salvage yard pretty cheap.
