Defective Blower Motor Resistor Pack.
There are a couple of reasons why a 1999 Oldsmobile Alero ac heater to stop working. The heater coil may need to be replaced or the HVAC blower motor may need to be replaced.
Blower motor NG. Blower motor resister NG. Blower motor fuse NG. Blower motor switch NG.
Blown fuse, defective blower motor, or defective blower motor resistor pack.
Check the fuse and relay first. Then check the blower resister, then the blower motor itself. One of these is probably the cause of the failure.
can be the heater blower motor resistor located in either the ductwork or under hood near blower motor on firewall
The most probabale cause for this sympstom is the blower motor , blower motor relay, or a fuse.
sounds like blower motor resistor. they are about $30.00 from the dealer
Blown fuse, bad heater blower motor control switch, bad blower motor, or a bad blower motor resistor pack.
The most common problems will be with either the power or the ground going to the the blower motor.................
No, that would have no bearing on the blower motor. Check the fuse, blower motor resistro pack, and the blower motor itself.
Check fuse if the blower is not working. If it is then replace your heater core. if its not then replace your fan switch.
Blown fuse? Bad relay? Bad switch? Burned out motor?
