k1500

I have a 1999 K1500 Suburban with a new engine, new starter, new battery (replaced twice) and still has trouble starting after long drives pulling a trailer of any weight. Haven't tried it without a trailer yet but I have two different trailers and it exhibits the problem with both trailers...

Hi, When I shift into reverse, the corresponding lights do not turn on. Thinking maybe they were burned out, I replaced them but still no dice. I checked the driver side dashboard fuse panel as well, all fuses are fine. Turn signals, brake lights, etc all work fine...it's just the backup...
