My 2000 Chevy Astro is not having instrument illumination lights.
I check the bulbs on the instrument cluster and they are good. I checked voltage from the 22 pin behind the cluster panel. The Grey cable is around 0.7v (I have no idea the number of the Grey on the terminal. I checked earlier chassis electrical system on Haynes Repair Manual 12-21 and found the Grey is responsible for the power input.)
Voltage feed checking:
Pink; Tan; Orange all around 14v
All others including Grey below 0.8v
1) with No ignition on
Grey; Pink; Green: 0;
Black 10om (is this the ground itself?)
2) with ignition on
Grey; Pink: 0
I also check the dimmer switch visually and found nothing abnormal.
And the gauges are working. PRND works too
Almost no vent (warm or nature) come out from front outlet, but out from the far end outlet on top of the dash (is that the defroster grille?).
I don"檛 remember when this happened because I don"檛 use it at night very often. And yet I did saw a smoke came out of the dash eight month ago. Because of that?
thanks for your time
have the same problem?
