yes i have a 1991 firebird formula 350 tpi all stock, and i have a few questions:

first when i turn my key to start the car the electric passengers fan comes on a stays on how can i fix this?

also i am installing foglights and my car can prewired from the factory so what do i need to install a factory foglight? do i need a fuse to put in the fuse block?

 

Does the fan come on when your A/C is off? Yor pass. fan is not supposed to come on unless your car is really hot, or if the hi side of your A/C is at a certain pressure. I am a little confused about your formula being pre-wired for fog lights. Do you have a fog light switch? Have you seen the wiring under the car? If yes, all you have to do is find the 12+ wire when your fog switch is on and hook it up to your fog lights. Also just because your fuse box has an open terminal for fog lights does not necessarily mean your car is pre-wired for them. Good luck.

 

Well lets say the cars been sitting all night when i turn the key to start the car the passengers fan comes right on, a/c turned off, and stays on so any suggestions?

As far as my car being prewired, i have the fog light connectors sitting wright next to the parking lights behind the nose, and i looked at my fuse panel and where i says foglights there is wires connected to the back of it but no fuse? i just wanted to hook up a factory switch like they would of did at the factory?

the actual foglights i dont have on the car yet.. and i have no stock switch yet..

 

if it turns on all the time it is grounded somewere more than likely. follow that wire off your fan switch and see if the wires is still in good condition.

 

the fan switch is the one on the block passeners side behind the knock senor right? i will check then
what about installing a stock fog light switch? do i need a fuse in the fuse panel?

 

my passengers fan still comes on when engine is cool, and i turn the key before the start the car??

also i noticed that my drivers fan never comes on at all, my temp is only at 220 and never goes over?

it also never comes on when i turn the a/c on, even though the passengers fan is still on, and my a/c needs to be charged??

 

Yes, the switch by your knock sensor if for the fan. But your pass fan should not be comming on at all if the car is cold. You should do a search on this board to get more info on your fans. I am sorry but I am not that good in this area and you have something strange going on there.

 

thanks alot for the help its was the temp sensor on the block.
