Customer Question

The service four wheel drive warning light is on constantly. The selector switch lights up when the engine is started but then has no lights lit when it is running. The vehicle appears to be in*****and does not appear to change when the knob is turned. Help! We have checked the fuses and checked for codes and all seems in order.
