My turn signals come on but stay lit. They do not blink. I replaced the fuse and it worked for about 30 seconds before the same problem came back

Second problem. My headlights work on dim but as soon as I press the floor button to turn them to high beams, they go out completely.

I'd like to have the entire truck rewired, but I'd like to get it operable first. Any suggestions would be appreciated.

 

Welcome to the site..

If both sides R&L don't flash, good chance its the flasher unit.

The dimmer switch is a common failure and could be the cause for the no high beams. Also, the connector at the dimmer liked to corrode. You can test the light functions bridging the connector before replacing the switch.
