Hi,
A newbie here..first post! Just purchased a 2000 Sunfire GT and the instrument cluster/heater/AC lighting does not work. (all my warning/idiot lights, speedo tach etc. work fine - just the back lighting doesn't) Here is the weird thing...if I turn the HL switch on when the car is NOT running, they work. If the car is running, they don't. I was looking at a wiring diagram in a Haynes manual, but it seems pretty generic. My question is, does anyone know if the cluster lighting works through the BCM? Everything else seems to work fine....
sounds like it might be a bad bcm.

So, they do run through the BCM? ugh.
