Hello all in am new to this forum. Name is David and I have a 2000 Chevy Silverado 1500 Lt with the 5.3 not sure how to explain this but i will do my best Lately for some reason my electrical has been messing up. it is almost like i have turned the key off and back on. The whole dash "resets" itself The seat belt light start flashing, the odometer goes off then back on,etc. but the engine does not miss a beat. I have check the battery cables and tighten them. Any ideas on the next steps i need to take?
