Cliff, here are schematics for the 86 GT.
Check the ground in the right rear wheel well, under the wheel well liner.

FanE fuses turns On the "logo" lights in the back when car is On.
Many times when have a Sneak Path w/ Tailights or front lights. Lights are "On" but dim maybe too dim to see thru the fixtures.
Pull 1 or both Taillight out then pull bulbs out of that to watch them while try test brakes w/ parking lights On & Off etc.
Sneak path ground can make Both side of 2057 etc to glow dim.
But may not help because sound like is "rerouting" thru High Brake. Try discon that bulb. Do Not Touch this bulb! Halogen will fail from any oil from hands etc. If touches must clean w/ alcohol.
While High Brake isn't On like many other Halogen bulbs, Long Stop Lights & bad traffic can have the bulb hot enough to blow the glass.
If have real Quartz glass the glass can grow until is very thin & pop but before can grow hitting the fixture & melt that even worse.

I checked again and the tail lights are on, just very, very dim (hardly visible). Isn't there an easy way to test this? By just routing a (temporary) ground wire to the tail lights? If that works, that would get me through the winter until warmer weather. Right now it's just too cold and wet to work on the car outside.

If is a ground then yes just tap a ground to any bulb socket & ground to frame anywhere handy. May find other bolt(s) there & loosen to stuff a wire under the head.
To avoid cutting wires... carefully uncover the back of sockets or release the ground "pin" so you can twist new wire to the socket "pin."
Or can use various "vampire" taps like https://www.amazon.com/Lock...-10-22/dp/B00CMC5DII that I believe is weather resistant unlike most others w/o silicon grease.
Likely can find same/sim @ amazon.nl etc search: wire tap connectors.
If clean the other end & "grease" the spot w/ silicone... little point digging out the other "official" ground.

I had checked all fuses yesterday and all seemed okay. Today I had to do a short 10 minute trip and noticed the dashboard lights were now out as well. I'm not sure it's related to the other problem or that something simply got loosened when I was checking the fuses.
But needless to say I'm getting quite frustrated with my Fiero... It seems that for every one thing I fix, two other things break...

Make sure it's not something simple like the dimmer being turned all the way down. Hey, it happens!

That was actually the first thing I checked. 😁

Just curious, how are your headlights doing? Also, what is the condition of your battery? Your alternator?
