take out your light switch and dry it using an office duster. put it back on an hour later. see if that fixes your problem

LCM is in failsafe mode. You may need a new one. If drying it doesn't fix it, send me a PM. I've got an uncoded LCM that I can sell pretty cheap

I tried drying it with an office duster, it did not work so I bought a new switch unit from eBay for $40, if that don't work I'll try the LCM, thanks guys

My Ride: e46 2002 2.5l
Hi,
I am having a similar problem.
On my 325 2002 e46 some water leaked through, now one of headlight's comes on when I do the following for 2 minutes and then turns off :

1. Unlock the car via key remote
2. lock the car via the key remote
3. open a door.

Any ideas if this is related to the lcm?
