Ok soI have a 98 neonwhenever I turn my front or rear defrosters on my car squeels like crazy and when i turn it off then its fine what is wrong with this thing??? I've had so many problems with this car I can't wait till I get a new one in spring

 

the heater motor is goin bad

 

Need to tightin your alternator belt.

 

what??

 

Tighten your alternator belt, it is loose.

 

is it expensive to get done? cuz I have a lot of other work going to the car i might just get rid of it

 

i dont know how the heater would affect your alt belt but tightning it up is easy is a 15mm wrench on the side to loosenand a 13 on the rear to tighten then tighten the 15

 

there is actually a 15mm swivel bolt on theside at the bottomthat you can get to through the wheel well....
then you have the 15mm bolt lock bolt on the side at the top.....
then there is the 13mm bolt on the back that actually moves the alternator to tighten/loosen

the rear defroster takes a good deal of power to have on....when you turn on the defroster, the alt. belt will sumtimes squeel from haveing to work a little more....
mine does it when i turn the heat on....then when i turn it off, or get the rpm's up a little, it goes away

 

Yeah, when you turn on that defroster it builds up resistance in that alternator and loads the motor down making it harder to turn the alt. so it slips.

Tighten the belt, see what happens, if not, time for a new belt then.
