2012 Jeep Compass - Headlight & Blinker Not Working

The fact that the light is dim suggests something is limiting the current flow, but it is not entirely disconnected. In other words a bad or corroded connection somewhere. All the connections in the circuit have to be considered suspects, including the ground (as above), the connector to the fixture, etc. If the ground screw isn’t the culprit (and that’s the place to start), the next is the connector(s) near the light fixture. If I had this problem I’d probably start by back-probing the voltage at the bulb connector. As posted above it might just be a problem in one of the control modules too.
