Under the dash on the passenger side you will find the "resistor pack." This can be tricky to get to but sits up behind the fan so you have to take that out first. The resistor pack, if it becomes hot will short out and will not allow all fan speeds to work since this is what controls the different speeds. This needs replacing. Also, my recomendation is to alos replace the in cabin air filter as this may be the cause of the resistor pack overheating.

Good Luck!

I have a 2003 dodge neon..and the rear defroster doesn't work..it has a button for it..and it just shuts off and back windshield doesn't clear at all...even if I keep turning it back on it...


Yeah, I'd think it would have lines, too, unless some new way of doing it that I'm not aware of. Maybe the rear window was replaced with a window without the defrost option. There should be a small two wire connector coming out of the back shelf near lower driver's side of rear window. That would be the defrost connector to the window lines (that aren't there,lol).
Well, good luck with that! I think there are aftermarket kits for rear window defrost, though.

I have a 2000 olds alero and first the back


It sounds like an electrical nightmare. The rear defrost and the blower motor are probably not related. The fact that the blower motor only runs on high is because the blower motor resistor is bad. I'm guessing the blower motor is just worn out that's why that quit. As far as the turn signal problem, not a clue there, maybe a bad ground somewhere or you're getting feedback from another circuit. Electrical problems are tough enough when they're right in front you, let trying do solve them via email. You need an electrical wiz for a mechanic.

No high speed on fan for heat and air


Replace your high speed cooling fan relay with a known working relay (rear window defrost for instance) and see if the fans turn on while the air is on high. If so, you need a new relay. You can also look into the fuse that protects the relay circut.
