plugged in a buddies trailer and heard a zap and my running light on my drivers side immediately went out on my durango. tried replacing the bulb with no luck. checked the fuse and it is fine, checked the connections hooking up to the light and they were getting power. replaced the bulb board and still no luck! Im over hear scratching my head! anyone have any ideas?

If you have towing package there should be separate relay/fuses for each side. Some of Chrysler products newer than 06 have a TIPM which is "totally integrated power system" and when it trips the dealer has to reset, only good for two resets and pretty expensive to replace so be sure the problem with trailer is resolved before trying it again. b
