hey I have a 2010 dodge nitro. Im having trouble figuring out this problem. My passenger side headlight isn't working. I swapped the bulb with the driver side headlight and same results. The high beam works but no low beam. I checked the voltage at the socket and im only getting 3.7 volts to the low beam socket. I also traced the wire back to the fuse box and everything seems to be alright with it. Any ideas on what could be wrong?

Thanks JR

 

Check it at the socket terminals AND at the wire a couple inches away. Compare. The TIPM module is the output source for the headlamps. No fuses.
