It may be a blown fuse. If you have kids, maybe one of them unplugged it for you. Look at the rear window. You can see where it plugs in from the inside.

AnswerI had the same problem and discoved that there is a module where the FM entenna (it's in the rear window) and the defrost are plugged together. This module was the problem.

How do you set the clock in a 1999 Oldsmobile Alero? I did not receive a book with the car and I really would like to have the right time in my car.

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.

It should, yes. That would be normal operation.

The Alero is made by Oldsmobile not Chrysler. My first suspicion would be a failed fuel pump or clogged fuel filter.

The RPMs and the engine of the 2001 Oldsmobile Alero might surge if there is a problem with the oxygen or fuel sensor. It may also surge if there is a problem with the fuel injectors or the fuel filter.

a bad sensor. the alero is notorius for many bad sensors. not an expensive replacement though

It would depend on which defrost system is not working, the rearview mirrors, back window or front window.

Generally not. Your best bet would be go to a wrecking yard.

because there is a problem with your anti-lock brakes

I doubt it. I have a 01 Alero that had to have a new fuel pump at about 100,000. If you have a leaking regulator, you need to replace it. It is a fire hazard. The symptoms for the bad fuel pump were normal function then it would just stop working. When it cooled down it would work again.

I believe that there is no mechanical speed governor. It is controlled by the PCM which you would have to reprogram to increase the limit.

User Avatar

well it depends on what year it is i would say so because my mom has a 1988 oldmobile!!!

General Motors products do not use inertia/reset switches

The most common cause for the defrost not properly working is a malfunctioning blending door. The blending door might be stuck halfway open. This would cause the defrost not to work unless the fan is on high.

The 1999 Oldsmobile Alero does not have Freon in the A/C system. It contains R134 and not Freon which is R12. As I am sure you do not have the proper equipment to recharge the system plus the fact it is illegal to add refrigerant to a system with a leak, until the leak is repaired, take it to a professional and have the leak repaired. You have a leak or you would not need to add refrigerant.

it could be numerous posibilities. i would have my timing checked, and also m vaccum hoses, there may be a leak.

The cost to replace the head gasket of a 2000 Oldsmobile Alero costs between $20 to $190. This depends on where the part is bought, the brand of the park and any costs concerning labor or shipping.

I have a 2003 alero. It has a power window circuit breaker on the passenger side fuse panel. It is located between 2 relays. I would check that first.

If the car has high miles, try checking the catalytic converter. If it is clogged it will cause the vehicle to lose power.
