I've an 83' F150 XLT where the rear/left (R/L) turn sign/flasher/brake lights won't work. The F/L lights but don't flash, R/L doesn't light, Right side front and back work fine. And to add insult to injury the R/L parking lights work! I have replaced the bulbs (front and back), replaced the flasher, checked the uhaul trailer connections on the R/L side, checked the ground connections on the F/L. Truck is due for inspection next month, HELLLLLP!

 

Thanks for all your help (not)! Plz delete this thread....
