I purchased a "rebuilt" instrument cluster for my 2006 F-150. Got it within a few days, installed and found that 1 of the gauges was not aligned properly. The voltage needle pegs to the right when I turn on my truck and in the off position, it is pointed up. ISS sent me a different one to replace that one. After installing the new one, 2 of the gauges was off. Engine temp and voltage gauge was both off. Just to be sure, I put the original one in and all gauges was correct. The only issue with the original one was the LCD screen didn't provide the milage anymore. So I really didn't want to mess with doing this all over again so I took the 1 with the 1 temp gauge and sent the others back. I would of thought these had been tested thoroughly.
