I own 2 Envoy's 1 is a 03 and the other one is a 05 my 03 oil pressure and tach. Gauge messes up from time to time. . . My 05 oil pressure and speedometer doesn't work. I called GMC and they said to contact you. . . My air bag light stays on my 03, I'm guessing that means it won't work if needed. . . . .
