rightside taillights out, replaced bulb's but still out, could this be a fuse, and if so which one would it be in fusepanel and amp.
tailights on 1990 Chevrolet G Series Van (G30)
There is no fuse specific to the right tail lights on your 1900 Chevrolet G Van. If there is no power to the right taillight sockets then you will need to check for a open wire in the light circuit. The power for the tail lights should go the the back on a single wire. If the side is OK then the fault should be in the rear of the van. Check the wiring from the left rear to the right rear.
