Right turn signal does function. I have replaced the switch and the front and rear bulbs. Can't seem to figure this one out. Because the problem is intermitent. Sometimes it works some it does. Most of the time it does work. I thought about replacing the turn signal relay, but when I call the dealer for the part they said it could be the BCM (Body control module). The BCM is way more expensive then the relay. Am I on the right track? Should I just keep replacing parts until I get the right one? Help!

Hello .. thanks for the donation .. much appreciated

The signals are controlled by the combination signal/DRL module and the fault could lie in this .. there is no relay in the standard term's ... do the front and rear bulbs flash at all ...?? I'm thinking you may just have a bad ground or hot feed on the right side front/rear ?

Hope this helps .. let me know

The right side functions with hazards, front and rear. Replaced the DRL module today, no change. Found a grounding point off the front unit on top of the right wheel well and cleanned it up, no change. Is there a different grounding point for the rear? If so where is it located? The schematics I have shows every thing going through the BCM. Is this my problem?

I couldn't see your schematics very well. They look better than my ones out my haynes manual. Could send them to me in a different format? Or maybe to an email?

Hello.

The 2 wires (20/21) from the BCM go to the message centre on the dash display not directly to the turn signals .. also can I check this is a caravan not the grand caravan ??

See if you can see these diagrams better ... you could left click your mose button and save them to your computer to resize them ? I have included a diagram of the ground points !!
