Dashboard Idiot Lights

First time on, so "be gentle with me". The dashboard lights up like the spacship in "ET", and then the idiot lights go on and off in a random way. Doesn't affect the way the car runs, just very disconcerting. Any idea what's up?

Thanks

sounds like one of the modules is loosing communication or the instrument panel is loosing iether power or ground. check for codes and if there aren't any - check feeds and grounds

My 2001 flashes the lights occationally but only when I turn the key from the run position to the accessory position,after stopping momentarily in the off position.If anyone else has had this problem,please inform me of the fix.

There is a TSB for the Pulsating dashboard lights (headlights too). I think is was caused by a bad ground. They fixed mine in accordance with the TSB!!!

hi, can you tell me the TSB number? do you know if it applies to 2000 silo's out of warranty? mine has 74000 miles

I believe it is TSB 01-06-03-005.

It involves replacing the ground screw on the alternator. I did mine in about 30 minutes (would have been faster if I knew where it was first). The "kit" (from GM dealer) was about $4.

Take care,

Thanks, but I'm afraid the dealer over here already got me for $375.00, and I'm not sure what was or wasn't done

thanks for the tsb info, will try to get at a gm dealer, hope it solve the up and down random fuel guage readings. i am having a problem with a flashing door ajar warning signal. the interior lights all work fine with opening and closing doors and the door switches seem to make perfect contact. do you have any ideas about the door ajar problem?
thanks!

No knowledge, but I know I really have to SLAM the doors when I close them.

I need some assistance regarding the same issue with pulsating dash/headlights for a 2000 silhouette. I bought the GM part (as described in the TSB) but unable to locate the grounding screw after removing the plastic wiper cover. Can't see the screw while looking straight on the alternator.

Any help will be good.

Thanks.
