On a recent trip, my 05 Denali oil pressure gauge went to 80psi (the stop) and stayed there. No other issues, runs as normal. Gauge went to zero with ignition off, but went back to 80 when turned on again. Sensor? Wiring?
I'm a new owner of an '05 Yukon Denali. The rearview mirror (w/OnStar) seems REALLY dark. The temp and compass light up I assume normally. Is this normal?
