I had to replace the mylar circuit board on the back of my car's gauge cluster. The car ran great before I began, just some dash lights didn't work. Now that everything is back together in the dash, and all the dash lights work, the car is totally dead. Everything else seems to work (fan, lights, wipers) except the car won't start. I did notice when I turn the key on the temperature gauge pegs at maximum. Does anyone have any idea what might be the issue?
