  1) I used this youtube video
  You Tube
  to try and fix my illumination problem. Turns out it didn't work for me. I pulled the panel out and tried the trick after seeing that it was unsuccessful I tried it with other wires in the same clip as the video. When I gave up I put everything back but when I went to work the next day the speedometer was unfunctional.

2) These lights haven't worked since I got the car. For the cluster, all the lights work except the ones for the gages.

3) When I'm driving after about 30min when you step on the gas (I have a heavy foot) when it normally accelerates it starts to jump. I'm not sure how to describe it, it like a jerking motion. It stops when you let go of the gas and then ease into the desired speed.

4) The turn signal flashes fast; I've checked all the fuses and all of them are there and are fine. I have changed the bulbs for that whole side.
* Needs a knock sensor replacing soon

 

Does the check engine light function? Is it on steady? Does it ever flash while driving? Do you know if you have any stored codes?
Have you checked for a signal output from your headlight switch for you dash illumination? I don't remember, is your dimmer on the dash or the cluster? You need to check there also.
Good luck!

 

Check engine light works and is on steady no flashing. The dimmer is on the cluster.

 

Have you had the codes checked to find out shh the check engine light is on? You mentioned a knock sensor. If it is bad it could be causing all sorts of problems.
