I just picked up my 2003 Ram 3500 SLT diesel about two weeks ago. I noticed a small problem starting. Sometimes when I put my left turn signal on the right one starts flashing. Then the lamp out light came on the dash. I found my passanger side rear turn signal was not working. I pulled the bulb and it was not burnt out. I put it back in and so far it is fine. Has anyone else had similar problems?

thanks.

 

I've never had the opposite one come one, but I've had the lamp out on a bulb that wasn't burnt out. All I did was swap it with the one above it (on my 07) and no problems

 

I would swap the bulbs out and after that check the socket they fit into
