Speedometer not working Gas gauge not working
I have a 2003 YUKON DENALI XL. My speedometer is stuck on 30 Mph and the gas hand is not moving stuck on a little less than 1/4. I just put $50.00 of gas in the car and it stayed the same It did not move. Also none of the other gauges are moving. I also can’t see the mileage, Reverse, Park, Drive, Neutral lights nothing. Also before this happened I remembered the oil sensor was flashing and I said that can’t be right I just got my oil changed a month ago. Also the washer fluid was flashing saying I needed fluid. I need help thanks.
