When I start my car the fan A/C will only work on high. When I turn the fan switch to one of the 4 lower speeds the fan goes off and also rear defroster won't work and the driving lights go out when the fan is in the 1 to 4 position. Last week it would delay coming on but after a minute it would turn on in the lower positions but now it won't come on at all in the 4 slower positions.

i agree with the first answer..the resister do go bad...how ever if they go bad it may be a sign that the blower motor is beginning to go bad wich causes the resistors to over load in the first place....when on high the fan is getting full voltage with no resistors and able to over come the problem....

Fan motors are run alot, so the motor can eventually burn out. Happened to me a few months ago. I have a Bronco, so it was easy to replace, but the tight fit under the hood might be too much for you. If you can find it and get it out, connect some wires directly to your battery and try it out. If it runs like that, try shaking it or turning it different ways. It will probably cut out on you, which means the coil is melting. If it works no matter how you bang it, shake it or turn it, then you have a bad wiring problem or a bad switch. Go for the switch next. They're cheap, you can buy one and replace it to see if that works. probably about $12 for the switch. I payed $27 for my fan motor. Not a bad amount to pay considering mechanics will charge you $60 just to get a look at it. Then they'll charge you for parts and labor. The fan could be located in 2 different places. In a can under the hood that's attatched to the firewall, or under your passenger side dash board. If it's the latter, you've got your work cut out for you, so get started early on a day off and don't take breaks. Good luck! Oh, one more thing: Find the + lead to the fan and check the resistance to ground. If you get any resistance other than 0 ohms or NO LOAD, there's something blocking the fan from turning...a bird???

Sounds like a short. If the problem was only with the fan, it might be in the switch or the fan speed relay. However since other accessories are affected, it sounds like a wiring problem.

Ummmmmm, true?
Yeah that's my guess. I know that this is questions and you asked none so I guess that you are telling us the truth. TRUE!
OK you have a bad fan switch and, it would seem several shorts in your car. Take it to the dealer and let them run them down and fix them, you get a warranty with the work and they MUST return worn/replaced parts, so you can have them checked to see if they needlessly replaced parts just to jack up the price of repairs.
Then you can sue them and get the repairs done for free!!!!!!!!

Common problem on pontiacs you need a blower motor resistor block, it is attached to the side of the blower motor it dictates the speeds!

more than likely its the bearing in the water pump. It probably doesnt work anymore and its harder to spin. That probably explains why it only spins on higher gears rather than lower gears. try getting a new bearing or you might have to replace the whole water pump.

sounds like a fan speed resistor problem

buy a book on your car, they come in handy even if you dont know jack about cars, but someone you know might and the book will be helpful to them. your contacts may be bad or corroded, i think its what everyone else is sayen good luck

broken check water or particles getting to motor parts and switches>>> check for shorts

take it to get it seen about at a local shop, it could be a fuse has blown.
