I need a little help with my transfercase. I have a 2000 s10 4wd blazer with the auto 4wd. The buttons on the dash won't light. I was told it was the module so I changed that and no luck. I took to a mechanic and he said it is the transfercase motor. It is shorted out and probably blew the module. Does anyone know the part number for the transfercase motor. He wants like $400 bucks for one but I have seen some the internet for less then $200 but don't know which one I have. Can someone please help me. Thanks Brad
