When I start the car the gauges work normally. I put the car into gear and start moving, the check engine light comes on and then the tempature gauge, speedometer and tachometer quit working. Any ideas what this might represent?

You 1st step here is get the computer scanned for code/s, you have a problem within the engine management system to find out what's causing the CEL to come On.

Took in it and the code was P1687. This did not register on the mechanics code list and the Chrysler dealership want $100 to look into it further. Any ideas on where to start?
