How to turn off the rear compartment light on a 1986 fiero gt? It wont turn off. Light stays on and the


Pop your trunk. Look up at the latch assembly on the lid and it should be brass colored but maybe a fuzzy white from corrosion from a humid sealed trunk. On the rear facing you side is a black plastic switch assembly that is screwed to the metal latch. This is the switch that turns on the trunk light. When the lid closes the hook/striker should press this switch in but if it's worn/misaligned, it can fail to open the circuit and shut off the light. You can just remove the bulb to stop it from killing your battery and the Ajar light on your dash will go out when you shut the car off.

Good luck,

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.

Where is the brake light relay on a 1984 Fiero


Check the brake light switch. It's located under the dash by the brake pedal. Disconnect the electrical connector from the switch. Jump the connector with a paper clip. Be careful not to let the paper clip touch a metal surface. If the brake lights come on then the problem is a faulty brake light switch.

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.

Lights


1st thing to check are the bulbs, if ok (good idea to try a new one, sometimes the filament looks ok, but is not connected on one side, difficult to spot), 2nd check for corrosion, powdery deposits, where bulb makes contact w/ socket. If corrosion is present, clean up w'/ fine sandpaper, coat connection point (contacts) w/ dielectric grease to prevent corrosion. If all this checks out ok, take a look at the brake light switch mounted on the brake pedal, it may be shot and would explain no brake lights. Let me know what u find.
