I'm having a problem with just RH parking lights front and rear taillight They are OUT?. I have directionals and 4way hazard lights
I have checked bulbs, they all work when directionals are on. LH fine , RH directions fine
New flasher relay
New turn signal switch

Where should I look next ? Help!

 

There's a fuse panel in the cab (in the passenger side rocker panel) that has fuses for the RH and LH parking lights, should be a 10 amp fuse. Check that and see if it's blown. Look at your driver's manual for the fuse diagram, or google it, it's on the internet somewhere.


Mine would constantly blow out the RH parking fuse every couple weeks, and it took me forever to figure out why. The wires for the trailer plug had rubbed through and were creating shorts, rewired the plug and no problems since.

 

Fuse in

Lights on !

Enough said !

Thanks for your help !
