Rewire the fan to a toggle switch inside the car or just hook the fan up direct to your ignition so when the car starts the fan comes on

Which fuse goes to the cooling fan


there is fuse and a relay for the cooling fan.just turn ignition on and test all the fuses(some fuses will only work with the system on like headlights/tail lights).check the relay in the relay box(panel)under the hood.you may have a bad cooling fan,you don`t say why your checking the fuse.if you unplug the connector at the cooling fan and jumper a ground wire and power wire it should work.if not then you need a cooling fan motor or assembly.

How do i use the diagnostic tool (tools) in my 1987 Pontiac Fiero GT?


Your Fiero uses the OBDI system. Do you have a OBDI scan tool? A OBDII scanner will not work on your car. It is possible to jump across the A and B terminals on the ALDL connector under the dash, using a metal paper clip as a jumper. The trouble codes would appear on the dash as a blinking check engine light. If you wish, I can get the website that has excellent instructions on readidng the flashes to determine the codes.

My left headlight door wont open when i turn the lights on 1985 pontiac fiero


If you open the hood, behind the headlight assembly you will see the motor that lifts the headlight, there is a knob that you can rotate to manually to crank up the headlight until you repair it.

Before you put it up manually, turn on the headlights with the hood open and listen to see of the motor is making noise, if it is you can try a repair kit, otherwise get a replacement from the auto part store or junk yard.

Here is a handy place for Fiero parts including the headlight repair kit I mentioned:

1987 Fiero GT automatic trans. Won't turn over-ran fine the day before. Even with a jump nothing works, radio, lights, break lights. There is no click or anything when the ignition is turned even the...


So no power anywhere? Nothing at all? I'm assuming the battery is fine since it ran the day before.

This actually happened to me one time in my fiero

What is happening is no power is getting to the car at all, no power is reaching the engine, lights, interior, etc.

This simply or not so simply means there is a severed connection from the battery.

1) Check BOTH positive and negative connections, make sure the posts are clean and make a solid metal-to-metal contact and see if there is power yet.

2) Check the power junction area (or whatever it's called) in the engine bay (on the passenger side wall near the battery). There are red wires
and such which supplies the car with power in this junction area attached to posts and inside of black plastic connectors. Look for worn or severed wires which may have come loose over the years.

When this happened to my fiero, one of the wires corroded and came loose from the post where it was bolted on and attached to other wires.

Just reconnect the loose wire(s), you may have to crimp new ends or whatever, but that should fix it.

If not, start hunting for where the 12v supply from the battery is cut off. Use a multimeter and good luck!

Do your brake lights work? If not, Check to make sure the brakwiring is connected. Turn signals and brake are electricaly associated. Good Luck, -Ned_

Fuse blowing


I agree. I would start by inspecting from the tail lights wiring and move up. You will have to remove interior pannels to see the harness.
