On Beetles from '49 through '74, that metal shroud in the very rear of the engine has a fan in it, driven by the generator, which of course is driven by the belt in the front of the engine. As the fan turns, it drives air through the ducts on either side, and cools the engine. It also pushes air through the heater boxes that heat the cab of the car.

99 vw AC blower not working?

tested blower,ok. then tested incoming voltage to blower and found to be zero. the final step was to replace the blower switch. To replace that switch, the middle part of the dashboard, including the radio had to be removed. The ac and heater come in one piece. It worked fine then. I think, there is a chance that the switch could be just cleaned up and it would work, again I think.


Why would our 97 lesabre blower work sometimes and sometimes not?

If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.


Your ac want blow how do you fix it?

If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse.

Why will the heater on a GMC Jimmy not work?

Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.


Why would the blower motor not work on a 1995 Cadillac Deville?

The blower motors only work with the engine running. If the blower motor has three wires on the electrical plug, then the blower motor module is built into the unit & it's very expensive. Sometimes, you can tap on the motor with a hammer & it may work or slowly turn. If this is the case, replace the blower motor.


Where is the heater blower relay located on a vw sharan P reg?
