So the left side dash lights will not come on (Eng, oil level, and oil temp). A friend of mine said it might need to be solder and was looking for another solution on here. Also my speedometer bounces every time I turn it on never reads close to what I’m actually going. I replaced the VSS but that actually made it worse lol. I’m going to put the old back on and actually get a new gear that goes in there. Would truly appreciate the help thanks.

The left side dash lights not working is a very well known and documented problem.

The soldered pins separate from the circuit board after years of vibration. A simple touch up with a low wattage iron, not a gun, on the solder side of the board will resolve it. Just touch the iron to it until the solder liquifies then remove the iron. Don’t shake/move the board much as it cools.

It could even be bad bulbs too, unlikely, but are you sure they are not removed?

I’m not sure about the manual, but if it’s auto, you have two VSS. The one you mentioned, with the gear, is what drives the speedometer.

If it fails it will use the other as a backup. Or maybe vice versa. Either way one or both are likely bad. I’m sure you have a check engine light but since it’s on the left dash cluster, you don’t see it.

You have a couple of issues that is making this more of a pain than it could be, get the left side lights fixed first.

Read about the pink wire fix going to the odometer.

Also, maybe good to read about leaking capacitors in the ECU.

I also have this issue with my left telltale.
I took the part out to check the solder connection and looked at the bulbs. Both looked fine. My brother tested it with a multi meter and it also seems fine.
Is there another way of reading the check engine codes? I have an OBD1 95' NA.

If the bulbs are good, this problem is always either (1) cold solder joints (which you can't just test with a multimeter, or (2) corroded contacts where the bulb wires contact the copper plate on the board. Use a clean pencil eraser on the copper contacts (with the bulbs removed), even if they look clean. Then touch up each and every solder joint (or have someone who knows how to solder do it). 100% fix.

Yes, an OBD1 code reader.

The speedo most likely needs new capacitors. Do a search. Stu Hagen sells them. Mine went out and I had to solder in new ones. All is well now.
