well i plugged the new dimmer switch in still does the same thing,so i'm returning it and using the old one. i got to drive the truck last nite didn't have any dash lites at all,then they came on by themselves.but i noticed that the oil pressure gauge was only showing 35 lbs at 55 mph. but with the lites turned off, just did this few minutes ago reved it up and the oil pressure gauge showed me that it was working showing 40-45lbs of pressure or better. the windows don't work now when the key is turned off either like they were.
don't know where to look or what to do this is crazy.does anybody have an idea on what to do? or look at?
