Bad turn signal 385 Peterbilt!!!! Need hep!!!!

Hey their truckers

I’m having a issue with my right side of my turn Signals, lights work just don’t flash. Neither do right side brake lights. Had a mechanic fix it but as soon as I got a couple miles down they went off again. Took it back to the mechanic and couldn’t find no broken or open wires. Now it’s just burning the fuse and I replace it on repeat.Have all LED lights except the front turn signals if that makes any difference. Any help will do if you have any information with this issue thanks!!!!!

 

Yeah I tried moving the wires around while parked to see if it will blow the fuse to see if theirs any kind of short but wouldn’t work. But as soon as I’m driving it works but seems the more I use it or longer I have it on it will go off blow the fuse. Light will still work just not blink and light indicating right turn come on.

 

Only while driving and putting the right signal can I make the right side go out (as in no longer flashes). So I just keep replacing the fuse in order to keep driving. Can a loose bulb cause this?
