Crazy flashing headlights and all dash indicators lit

[tcmdr23]

03 GC 3.8l "ALL" of the dash indicators will come on while driving or even sitting in park at idle. The headlights will also go on and off or even strobe! the vehicle still drives fine but nothing on the dash works. Help! This is a random occurance dry or wet weather.

You may start by ck'ing for stored codes in the bcm or cluster.

I just bought this problem, 00 ram van 3spd v6 off my friend. I know they were working about 8 days ago.
He told me that the headlights were flickering, and now do not come on... he didn't know what the problem was.
I tried looking to see if there was an exclusive headlight fuse, but I couldn't find anything in the 2 locations known - left side dash board driver side, and next to the battery. all my other lights work properly.
I found this, 'multi-function switch going bad' statement...

Disconnect one of the headlamp connectors and using a test lite, see if you have any power coming from the switch when you turn it on. if you don't, you may have a open circuit. The Ram Vans also had a fuse box inside the glove box too. My guess would be a head lite switch or multi fuction switch.

ya, I pulled out the headlight switch, turned it on, no current was passing through 1 hot point. upon disconnecting it, I saw some black carbon on that connector.
Bought one for $30 at autozone, (sw220). fixed the problem. I take it that it's a common issue.
