My '84 & '86 front trunk lights weren't working. I've never needed them - but they're there so I thought I should fix them.

While at the Glendale Auto Parts U-pick for the ignition module, coils & crank sensor assembly ($20!), I took out the hood switch (free). I could see why the two at home were not likely working: corrosion. You can see in the pic below that there are two angled surfaces that contact the cone by spring pressure to complete the circuit. The pliers are holding the contacts open as the hood does when closed; the contact surfaces eventually become non-conductive with corrosion.

With a good bulb in the socket, and the tail light switch on, twist the switch striker button back & forth a little until you wear the corrosion off & the bulb will likely come on.

Did all models have lights in the front trunk ? I did not know that , were would it be located if so?
pics would help if possible thanks

If your car has a switch near the latch mechanism hole as shown here:



look for a 194 push-in type bulb & socket between the HVAC motor & the windshield washer fluid tank as shown in the pics in fierogtx's thread just above.

I think the light was in all cars. My '84 SE, '86 base Coupe and '88 Formula all have it, although the '86 doesn't have a bracket - the socket just hangs out of the wiring harness.

Many might suspect the bulb is burnt out while in reality, it may never have been on. It's more likely that the switch contacts are corroded and/or the hood has never been opened when the parking light switch is on.

This I do have never noticed it before

This however I do not , I did find the socket after looking behind things


but never found the bracket that holds it, also no lamp.
That is why I never noticed it , no light and I never looked for it.
Thanks

I replaced the bulb on mine but it was corrosion and not the bulb. I took a tooth brush and knocked off the corrosion and I think I used a bit of wd40 on it. Works like a charm now. They work only when the hood is up and the parking lights are on.

my 85 SE has the brackets for the internal lights but there are no sockets or wires that appear to have ever been hooked up. The trunk has a gray cover plate over were the light would be and nothing in the front trunk area. The plungers just activate the AJAR dash light .

I 'upgraded' my base '86 coupe with the interior & trunk lights & the dash power deck release as follows:

I got the interior cross-car wire with a plug & two sockets that fit the existing mounting holes from a parts car; the plug was different so I adapted it to the existing connector that was hanging from 2 white & one orange wire by the fuse panel.

I got the trunk light wiring & ran it under the rubber trunk seal to the battery area. The wiring is easily fished through the existing holes. I got a new trunk light assembly from The Fiero Store.

I got the trunk release solenoid, wiring & switch which plugged into the exiting instrument pod harness and the rear wiring harness connector already there. The wiring is fished through the decklid.

Look closely in the front compartment on the passenger's side - you may find a small socket just hanging from the wiring harness for a 194 push-in bulb. It might be tucked behind the wiring harness.

problem is switch is "indoor use only." Corrosion and breakage are common when used in hood/trunk areas.

Get a new Jamb switch and lube it and contacts w/ brake, bulb or dielectric grease.

Jamb switch will self adjust first time whatever is closed.
Can be order thru many places... RA, Advance, etc.
