Problems with my turn signals staying on

Hey this happened to my 2018 Coronado I had a signal light out, turn your lights on and the signal that's not working and walk around the truck and see if it's a light out

 

Bad quality bulbs. Pay a little more and get brand name bulbs. #3157A.

 

My 2000 Classic has an intermittent dim right turn signal indicator light on dash.Everything works as should otherwise. Just running down the road w/ headlights on, it appears and is dimly fading in an out somewhat. Unplugged trailer same problem.Trying to stay ahead of it. Last time on another Truck it was the 7 wire from fuse panel to rear pigtail receptacle. I’m thinking that or, turn signal( which I’ve redone a couple times due to right signal not working, weak spring inside).Or maybe a dash light problem. Hoping it’s not the 7 wire .

 

When i turn on my lights on my freightliner century 2003 and put down the left turn signal don't work, if the lights is off the left side signal work

 

Did you ever figure out the issue, my 2016 just started this

 

No, it quit doing it. Recently started to do it again. Then quit. My last Truck, one of the signals would stop working, can’t remember if it was left or right. Mechanic at Freightliner told me to unplug the indicator and plug it back in. Sure enough it worked. Said he doesn’t know why. I had to do it a few times. A common thing is right not working. I’ve taken the turn signal arms apart a few times on different Trucks over the years. Bend and stretch the 2 different little springs, tightens everything up, add some grease to everything. Usually it’s a only a problem with right position, since it’s in the up position and gets loose over time. When in left turn position, it doesn’t move around.
