Story- I have a 1987 GT, 2.8 5 speed. I was changing the cluster lights for some LED since some of my original lights weren’t working. In the process I’ve noticed my PCB was corroded so I try to fix it with no hope. With the “fix” PCB my trunk release button stop working and would only illuminate the brake light ones triggered. Also my seatbelt light would stay on only for some seconds then turn off, the light also seam weak even with the new LED. With that I ordered a new one from deloreangarage and ones everything was put together, lights didn’t work. My trunk release button won’t release, my ajar light only come one when the ignition is turn, my headlight indicator light doesn’t work. The seatbelt is still doing its thing.

Looking for some evidence on the matter. I’m leaning with bad fuses or bad grounds if so where should i start. I’ll answer any questions about the matter and the vehicle.

Seat belt light will turn on every time you turn the key to start then turn off. If you don't have seat belt on will chime too or have cut/mod the seat belt etc to stop that.

Good luck jumping on LED hype train claiming LED solves everything...

I had change the light that aren’t working back to halogen to see if the issue was resolved and it did not. With halogen or LED. I’ve read the cave form you gave me it seems I’ll run some test with a multimeter I’ll be check/replacing my fuses since they are 37 years old.

194 bulbs are Not Halogen. Even when replace w/ Long Life bulbs. Unless Maybe someone found halogen 194 or just put hotter bulb in same format.

when have "Dim bulbs" or other dash problems...

https://www.fiero.nl/forum/Forum2/HTML/146784.html Fuel, Engine Temp or Oil Pressure gauges have problems?

Example: can have a brand new bulb but have crap sockets &/or "crush" dash back where socket "arms" hit won't connect the bulb to the back of dash.
If the back is "crushed" just moving a socket even tiny bit can make it work.
or socket "arms" are cracked/broken & won't touch the dash back.
or socket "guts" are bad can't reach the bulb wires.

Can get 10 pack of 194 as need 6 to replace just dash illumination bulbs.

Thansk for the information. I just when to check my dash light and I’ll say I’m not a big fan of the LED. I’ll probably be getting some red tip bulbs for the dash. I also did some digging and found some good info on the electrical network of the car. It was a lot of information all at ones but I should be able to figure out wast wrong with my lights and dash. Like I say I’ll probably be replacing the fuses since they are pretty old and get new light sockets for the dash. Also maybe you know anything about the shifter light. I driven the vehicle before but not really fast and only around the neighborhood. Oh well if it doesn’t work then so be it. At least all my gauges work( the important things)

The Shift light is nothing but a nuisance and a distraction. And it's got nothing to do with going "fast". It's an indicator for driving as economically as possible.

That + helps drivers not to shift @ "red line."

Reminds some w/ auto & stick cars you driving the stick that needs you to shift.

When comes On, sometimes it seems random & short trips in town may never turn On.
