messed with gauge cluster, screwed it up.

Ok so over the weekend, I had the bright idea to put blue lights in my gauge cluster, long story short, after 4 advance autos, I had 4 blue 194 bulbs and a blue led that would fit. So I tore the cluster out and the plugs were very hard to get out and were pulling the printed circuit out a bit. Finally got em out and pushed the circuit things back in. Put the new lights in, not bright enough, so I tore the cluster apart and got the green coating off the back of the gauges, put them back together,and had the needles where they were (I thought). Now my oil pressure gauge is above the H, my speedometer isn't working, my tach is at 1000 and will jump straight to 2000, and my over drive light is blinking. And it revs to 2000 before shifting in 1st+2nd. WTF did I screw up?!

Wow that sucks.... Sure glad I made all my stuff green to match oem

You should try pulling it back apart to see if there is an obvious plug issue on the plastic circuit board sheeting inside the main harness plug hole. Since the speedo is driven through the PCM, sounds like a short. I think that you'll be needing to find a new cluster and hopefully you didn't jack the PCM. Yeah, those clusters are very fragile.

One of the plugs isn't fully seated into the cluster or you fuggered up the printed circuit board.

Yeah I'm gonna tear it back apart when I get home this weekend. If I did screw up the circuit, anyone know where I can get a whole new cluster?

Junkyard but make sure to get one from a 96-97 as the printed circuit board changed a few times.

Ok I figured it out. Took my dome light off which blew the fuse for the speedo and the shift solenoid I beleive. Never would've guessed that would be on the same fuse as the dome light. Now she shifts like she should, just have to readjust a couple guages
