Problems with my turn signals staying on

Thank you everyone for the help and for those who may have this same issue down the road. It did turn out to be a bad ground. The electrical cord running from the truck to the trailer was bad and grounding out before it plugged into the trailer. Bought a new cord for 65.00 and it is working like a champ again.

 

Melvin when you say cord. did you mean pigtail cord? Im having the same issues.

 

7 way truck to trailer electrical cord (usually green)

 

It's the Turn Signal switch. Just replace it. Take about 5 minutes.
I had weird stuff happening. I was splicing wires here and there and a guy on the forum suggested replacing the T/S switch. I forget how much it cost. Under $100 I think

 

opps! Maybe I should work at the T/A

 

Help. Need wiring diagram. With light switch off I turn on right turn signal and all lights blink. Inc. Head marker dash Everything. Can't figure it out. Need harness diagram for lights. If switch is on then all lights come on but then right turn signal just comes on it don't blink and brake lights are always on if switch is on. And to be clear I mean the bright brake lights not just my running lights

 

Having same problem eith my 2007 kenworth. On front right light. Just turning off snd on intermittently


QUOTE="CondoCruiser, post: 3825904, member: 41921"]Your headlights run through your turn signal switch. There are little copper contacts in it and they can break and short across other contacts. That would be my guess.

You can unplug the switch and ohm it out. I think the right side is the Light Green wire and the Headlight Hot is either the Red or White wire.

The left side is the yellow wire. Your ohm check should be the same as the right side and show open.

There's like 3 different switches. If you can get the model number off it I can get the exact wiring diagram.[/QUOTE]

 

Steering wheel come off? 5 minutes job?

 

I have a 2017 cascadia, the original blinker bulbs stayed the amber color, now that I have replaced them after about 2 weeks the amber turns white, like a clear bulb, why is it doing this
