My truck keeps blowing the right turn signal fuse. I have replaced the corroded and burnt front signal socket as I was told that could be part of the problem. Now another person tells me that if I do not have the oem flasher unit this might be the culprit. Have any ideas to the problem.

Rather then listening to people telling you it's this or that , if you can't view a wiring diagram an use a DVOM - digital volt ohm meter an test the circuits an find the problem , your best bet mite be to take your vehicle to a qualified repair shop. There are a lot of training videos on youtube for leaning how to trouble shoot these type problems . This is how professional technicians learned !

If the fuse blowes you have a direct short to ground on the B+ voltage supply circuit for the right turn signals .

When does the fuse blow ? As soon as you turn right signal on ? As soon as you install a new fuse ?

The clutch in compressor is controlled by a pressure switch. Start there.

it seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

The fuse is blowing from one of the wires shorting out to the tail lights. The best place to start is the trailer wiring harness. Check the trailer wiring and make sure that the brown wire in the trailer wiring is not shorting or have any bad places in the insulation.
