I have a 93 GMC K2500 6.5 Diesel... It has a few weird electrical issues.
I'll start, Batteries are brand new and I've checked those connections and they are clean and tight.
What's going on is, whenever I turn on my headlights my gauges go wonky. They move up or down a little from the normal positions. When I turn the lights off, my gauges go to a more "Normal" position (The only two gauges not affected are the tach and speedo)
Also; Whenever I turn my turn signals on, especially on the highway the speedo will jump around when I first click the signal on, but goes back to normal afterwards
Also; The passenger side window doesn't work from it's own switches... Works fine from the drivers side - If I use the switches on the passenger side door, all the gauges will jump around until I let go of the switch.
Any ideas?
