Qblue92

My 92 does this cute trick where the digital part of the dash gives me wild gibberish or it goes blank if the weather is warm or hot... I had it fixed once, and the guy told me the digital gauge cluster wasn't making good contact with the plug/harness behind it. I've got it loose, and I can't seem to get it out. I don't see how I can get to the back side of the cluster without removing the steering column. can I get to it from underneath the dash? Is there a magic word? help pleeezzzz!!

My 1990 does the same thing. It also pegs the tach out when you start the car. Did yours ever do that? My GM service manual says to remove the knee bolster and the bolts holding the colum to remove the cluster. I looked up and behined the dash for the cluster plug, but i could only find were the wires went into it. No plug on that side of the cluster. I was going to remove mine next weekend. Let me know about your tach.
Good luck.

No- my tach needle never freaks out. its just in the digital part.

I just had the digi out of my '88.

I pulled the dash & DIC bezels and removed the screws from the front of the IP cover pad. Then I raised the front of the IP pad enough to clear the IP when I tilted it forward. I pulled the left side of the IP out far enough to remove the two connectors in the right rear. I then slid the IP out from the dash opening over the steering wheel.

This procedure pretty much follows the method outlined in Gordon Killebrew's book on the digi dash.
