Hi,
I have been having a problem with the dash lights on my 1989 Chevy 3/4 ton pickup. When I turn on the headlights the turn signal lights will stay on solid, the gauges will quit working or peg all the way out, and the high beam indicator will show the opposite of what the headlights are actually on. I was thinking there had to be a bad ground somewhere under the dash. I have taken the dash panel out and cleaned the brass contacts and reassembled the dash but this didn't make a difference. Sometimes if I slap the top of the dash board the lights and gauges will pop back on and work fine for a while.
I have noticed it got worse when the cold weather set in this winter. Slapping the top of the dash won't pop them back on. After the inside of the pickup gets pretty warm they will sometimes pop back on by themselves. This 'working when warm' makes me think of a bad ground somewhere, but where?
Could a bad part somewhere be causing this? Anyone have any ideas? Is there anywhere that I can peruse service bulletins for this pickup?
Thanks in advance for any help!
