GM-GMC: my 88 gmc high sierra, high sierra, dash panel

Question
how do i fix my dash panel lights on my 1988 gmc high sierra 1500

Answer
Well, depending on what is wrong with them there are a number of things you can do.  First and foremost would be to check the fuses.  Look for one labelled ill, or int or something like that.  Second would be to check to see if the dimmer switch is not in the off position, next use a test light and see if you have power coming in to the dimmer switch.  If you do, perhaps you have a number of burnt out bulbs, in which case you can remove the dash panel and replace as necessary.
Hope this helps
