Well I just bought a Escalade overlay and one stepper motor and buld and I got everything disassembled easy, marked all the needles and soldered the new motor in and I know its installed corectly because it can only go one way and all the points are covered. And I noticed the bulb that I got has a blue housing and I noticed the other gauges have yellow and the ones with the blue are my warning lights. Is this why my light dosn't work or do I have to reprogram my cluster the make the motor work? Sorry for the long post anything helps.

 

Is is cold in Virginia.... won't move much in these low temperatures...

 

No its not that cold but I think the cluster has to be reprogrammed because I have noticed that when I turn the key forward all the other gauges jump then settle but my trans gauge dosnt even move
