You can check the bulbs or if you lay under the bed of the truck on the driver side you will see a panel that is straight up and down with about 4-6 connecters on it i dont remember how many there are but anyways take off the connectors one by one and look at the piece you pulled off and if its got black or brown parts around the metal slits it is burnt and youll have to get a new one but check all of them.
I changed switch after intermittent failure. Now brake lights stay on even with new switch unplugged. They do go off when truck is off. Suggestions? Thanks
Left light and turn signal stopped working, but the reverse light and running lights are working- so all the bulbs are fine.
Checked all the fuses- in good condition. Checked the junction box under the bed, but connections seem ok...? What now?
The brakes on my rv trailer ran hot and I had the shoes and magnets replaced. Question is: was it the trucks fault or the brakes on the trailer? What iis blown on the truck that stopes the trailer hook up lights from working. Stop lights, turn signal, side lights don't work on trailer but they do on truck.
