 Subject: 2002 Dakota - Headlight Problem - Help
IP: Logged
Message:
Hey guys, I'm new here and I'm in serious need of help
My 2002 Dodge Dakota Sport (4x4 6cyl) driver side head lamp won't work, hi or low beam. Passenger side works fine on both
What we've already tried:
- replaced headlight with known working (took out of passenger side where it worked fine, did not work on driver side), we also replaced with a new bulb (both sides, confirmed working on passenger side)
- Confirmed that there is no voltage at the socket when headlights are on, we get 12 Volts on passenger side, none on driver side this is both Hi and low beam
- Confirmed that we get 0 Ohms when grounded directly to the battery
- confirmed there are no blown fuses in fuse box next to drivers side door, did the same with fuse box in engine compartment. Although I'm not sure there IS a fuse for the headlights, we had head lights on pulled every fuse one at a time and the only time the passenger light went off was when we pulled CTM A fuse (Central Timing?)
I'm at the end of my rope here, I can't find a fuse for the passenger head light, I can't find anything that would cause the driver side to go out only (no other electrical issues at all in the truck). I'm about to take it to a dealer to "troubleshoot" but don't really have the money for them to poke around for a few hours on my dime
any suggestions or help that anyone can provide would be great!

Same problem here, No voltage to driver side socket. Unplugged harness at ctm located in driver kick panel. Hooked 12v to the Purple wire (low beam) at the back of the plug then took a voltage reading at the headlight socket again. Read 12v.Did the same thing to the red wire pink stripe which is the high beam.Again 12v at the headlamp socket.Harness is 100% So the bad news is that lil black box the ctm,Take the 3 harness plugs off,unbolt from body,undo the clips on the outside of the box and open it there is a P.C.board inside. You will see 4 square black diodes with 4 legs each. The first 2 on the left control the passanger side low-high in that order. Take a voltage reading on the 2 closest to the edge of the board and the 2 legs on the right it will read 12v on low when switching to high beam the voltage drops to 4.5v and the other 2 legs on the other chip become hot with 12v hope this answers your question. If ya aint got the money you could jump the purple and purple/red stripe together at the ctm out not recommended only emergency
