2001 Headlight problems

[B33p3r]

I'm a firm believer in making sure the cheap fixes are checked before spending bucks. My feelings are it's a bad ground connection somewhere. The obvious place to start is the battery. I know pulling the IOD fuse resets things, but it doesn't ensure the battery connections get cleaned.
When a BCM gets replaced, I bet the battery cable(s) get pulled, probably cleaned upon reinstall, (a good mechanic would) and the BCM is rewarded for fixing the problem. I have no facts to base this on, but it costs nothing to give the battery connections a good cleaning.
Also check light bulb plugs and such for good grounds. Anyone that ever owned a trailer can tell you what havoc a poor ground plays on the lights!
Good Luck!

Here is what I did with my headlamp problem. 2001 Grand Caravan Sport. The headlights were confused. (Left and right lights would flip-flop depending which mode you were in). I have a friend whom work at a dealership. He said check the ground in the floor by the B-pillar, next to the drivers seat belt. He said that because at least one light was working at a time, the ground should be good. Then he said it should be a "driver" in the IPM (intagrated power module.) I called our local "Dodge" dealer to price this out. The FCM (front control module) and the IPM are sold individually. About $550 for both units. I found one on Ebay for $30 "Buy It Now", it had the same serial/part numbers on the FCM. I changed it myself last Saturday and everthing is working fine. No more light problems. Daytime running lights and everything work great. I do have some literature from the Dodge dealer concerning TSB's on this condition. I will be more than happy to scan, email or fax to any of you. Hope this helps.

Trailer lights don't have computer systems controlling them.

Thanks a bunch. I disconnected the negative post on the battery for 10 minutes. Cleaned the post on each, reconnected, started and problem was solved.
