Ok so I have an odd issue, I will start at the beginning, and try to include anything that might be relevant. First off I have a 89 S-10 Blazer Tahoe. So last week I pushed my lighter in and my guages went heywire and the indicator lights for the turn signals and highbeam turn on and stay on. I turn off the headlights and everything works fine. Guages go back to normal, until I turn the headlights on, all dash lights stop working the same time the guages do. It seems to me that using the headlights short out the dash but not sure how that is. Checked all of my fuses everything seems fine. It has done this before about a month ago and I found something online about a ground screw in the lower left corner of the dash, but it seemed to have fixed itself before I had replaced that screw. But wait there is more.. when it has these issues the truck starts with a little resistance, but then the issue had gone away about a month ago the truck became increasingly difficult to start, to point of having to jumpstart it every morning, if the truck sat for more than 4 hours it would have to be jumpstarted. When I jumpstarted it, it would start instantly, on first turn of the crank. But now that I am having the issue again, it's been starting in the morning and after school in the afternoon. I greatly appreciate any and all help in resolving this annoying issue, since I have to leave for school every morning at 5am so I have no guages on my drive in.
