o.k.
So I removed the instrument panel and removed the (digital) odometer bulb.
It was indeed burned out,I took it to the dealer and the said they could not find it in their GM mainframe.The parts guy said he never saw a bulb like that.
I looks just like a regular bulb you take from a cluster.
Would anybody know where I can actually find a replacement bulb,without having to get a junk cluster just for the bulb?
