Taillights 91 crew cab

[scotto0609]

Ran into a problem with the cc the other night. Lost just the tail lights,directionals work,brake lights work,hazards work headlights work. So basically I lost the dually marker lights and the tail lights. Any ideas what the color the wires I am looking for that are bad. I redid the grounds out back and everything looks good until I get to the trailer harness but even that looks ok. thanks scott

The front and back lights are all grounded. Remove and cleanup ground connections. Sometimes you have to wire wheel or sand down were they connect to get good ground. Also check other ground connections. One goes from engine to firewall. Then check and replace bulbs.

I see u checked grounds. I replaced all the switches in my 89 blazer. Light, backup /neutral safty and brake. They seem to all function and rely on each other working. Cheap fix. Then of course the fuses.
