If I remember you have the socket that twist into the housing. Socket has three contacts? The contact on the plastic housing side melt into the housing causing poor or no contact. Try bending the contact up a little. You may need a new taillight assy. I think?
I remember we had a lot of problems with the rear taillite and turn signal housings that hold the bulbs and the circuit boards on pickup trucks. Many bad connections inside the unit. But I cant remember if the Caravans had many problems but they may have. Can you unplug the complete right side housing and plug it into the left side ? I just remember many loss grounds in them housings and boards. I know we replaced many of them housings/board units on the pickup trucks. Ron
