Wanted to drive in Dream Cruise tonight but don't have brake lights or rear turn signals. Front signals work as do do all other lights. Swapped turn signal stalk to no avail.

Suggestions please.

Possibly the ground connection for all the rear lights located at thr drivers side rear.

To expand on Wally's posting a bit. If it is a ground side issue, it also could be the crossover straps between the body and frame or the engine and the frame. A quick way to check this would be to remove one tail light lens and temporarily run a jumper with a couple of alligator clips between the tail light frame and the rear bumper just below. If it works, you have an open ground.

I'm guessing it is the turn signal switch.

Had similar problem when I bought coach. My CRS subsided for a minute and remembered he headlight switch replacement solved these problems. Just put in new headlight switch and have rear directionals but still no brake lights.

Also check all the connectors around the base/side/back of the steering column. Recently lost our backup
lights mysteriously -- discovered I'd neglected to hookup one of the connectors behind the column when I was working on steering...

Well. I think I got it fixed. New light switch, sanded bulbs and electrical cleaner spray on all connections under dash, also adjusted brake switch. Thanks for all your input.

When it happens again, clean the connections in the fuse block and/or change the fuse. Dash illumination and tail lights are on the same fuse. If you are driving at night and you got no dash illumination, you got not tail lights either. Manufacturers have been doing that for decades so the driver knows when the tail light fuse has blown.
