recently purchased car for son: blower control only works on high, when car is in park(with headlights on)you move blower switch, the headlights go off. what the.....is going on. help! mom not so happy thank you
blower only works on high, headlights go off on 1997 Pontiac Grand Prix
Usually thats the blower motor resistor is bad when the blower motor only runs on high, But the headlights going on and off needs to be diagnosed by a tech, You can locate a shop near you here www.repairpal.com/directory
If The Blower Resistor doesn't Fix The Issue, it is The IGNITION SWITCH, All Power For accy's go Through the Switch harness in The Column, Pitiful engineering...
