Resistor pack has failed. it is usually accessible from the engine compartment near all the A/C stuff on the left firewall. It looks like a little removable square along the A/c duct with wires coming out. The resistors stick into the flow of the A/c for cooling.

2003 buick Century air conditioning blower

Hi Ken, I'm glad to help! A/C Blower problems like your, where the blower only blows on HIGH and later stops working all together is usually the "BLOWER MOTOR RESISTER" That is where I would start. Ken, If that does fix it. I would replace the blower motor as well because its usually the high resister within the motor that actually causes the problem with the resister. The Blower Resister on most vehicles is located on the passenger side near the motor. Some are right beside the motor, others are behind the glove box in the housing. Hope this helps and have an awesome day Ken.

Blowers Stopped Working Focus 99 1.6 Ghia

check for power at the blower motor. then check if it has good ground . ground wire is black/orange and goes through blower switch, then to ground. If you ground the black/orange wire at the motor and it works, you either have a bad blower switch or wire connection (I do not have a diagram for your car, this is based on a 2000 2.0 focus) the wire ends up at the left A pillar. black wire.

Blower motor resistor

Yes the Red wire Commonly is the 12v power to the Blower motor.
If you don't fix the plug the blower will not work correctly.

But the best choice will be, if you replace the harnes connector.
Because is commomly burn for high resisteance on the blower motor.

Ok.. I hope this help on your question.
Sorry if I 'm late. but I was unable to check my Emails yesterday.

Hi there!

Replace the blower motor resister behind the glove compartment. This corrects the blower issue. Don't know about the door lock problem.

Heater switch only has hi speed

This was wrong with my 01 Stratus and it was the blower motor. Between the part and the labor to have it fixed, it was around $130.
