Question
BillGriff1
My 2003 Suburban began having intermittent instrument panel failures in July of 2005. While returning from vacation, the instrument panel did not work after starting the vehicle. Nothing on the panel worked at all. No speedometer, no gauges, no driver information center... not even an gear indicator. Radio, A/C, wipers, headlights, turn indicators worked properly.
As it was the weekend, I decided to continue driving home and take it in to the dealer on Monday. After driving an hour or so with no instruments, I heard a bell and the instrument panel cycled on and began working properly. I didn't take it in to the dealer since it was working properly, however, in a couple of weeks I had the same problem.
This time I took it to the dealer. The technician read the service code(s) and determined my instrument panel needed to be replace. While he was checking the codes, the panel began working properly again. With the significant cost of replacing the panel, I decided to wait on the repair.
I searched the Internet for information and found something that seemed to indicated the electrical system was highly sensitive to low voltage situations. I had my battery checked and found I had a dead cell. I replaced the battery and the problem seems to disappear.
Today the problem reappeared. When I entered the vehicle this morning, I noticed the driver's information center (DIC) was fully lit; each character position was fully illuminated... rectangles across the entire DIC. I started the vehicle without any problem... but the instrument panel is not working.
Any ideas? Any help would be very much appreciated.
