My 2016 Kenworth t660 has no turn signals in front all the others work fine

I've checked the chassis node fuses in the chassis load center and the fuses under the dash the bulbs were good and I don't see any broken wires anyone else have this problem

 

Did you change them to led. type if you put all led lights on you must leave one reg. bulb some where in the system to draw enough power to make all the led bulbs light up?

 

I only have regular incandescent bulbs at the moment and I bought 2led replacement for the ones that aren't working, and those 2 will be the 1st l e ds on the truck

 

Sorry thats what happens when your 3 sheets in the wind on a cook out day, were they blinking before you changed the ft bulbs, if you take out the bulbs and clean the contacts inside and get a test light and ck both ground and power contacts with 4 ways on then with each turn sig. on you may find the problem, i have found dimes and 1 cent coins down inside under bulbs from going to eat and tec. bent over and coins fell out of top pocket and into socket?

 

I've already cleared the contacts

 

My 2021 Kenworth had this problem, and it turned out to be a metal staple that holds the wiring harness wore through the wire insulation.
