Bad turn signal switch?
I just completed a grille swap. I fixed the DS turn lamp where the wires come into the housing, and both lights worked after I did this. However, after I pulled the right blinker out of its harness, I screwed something up.
Situations:
Lights: OFF, LEFT blinker ON = weak front left blinker
Lights: OFF, RIGHT blinker ON = no right blinker
Lights: ON = solid right blinker
Lights: ON, LEFT blinker ON = solid right blinker
Lights: ON, RIGHT blinker ON = solid right blinker
The rear turn lamps function the way they're supposed to, just not the fronts.
My question is, do I need a new TSS? Or should I be hunting down a short?

I had to trace this down once also. I assume your dash TS indicator stays on also when the front TS light does? First thing I did was check the ground at the sockets in the front . You can actually have a bad socket or ground that looks just fine from the outside. I replaced the socket and viola! All was fixed. It's crazy how one ground can screw up an entire system. Bottom line is you have a ground problem and not a switch problem. And of course tracing a bad ground can be a PITA! Good luck!

No, when you turn on your blinker the indicator lights on your dash flashes too. Does it stay on when the light bulb in the socket on the front of your truck stays on?

Yes it flashes on the dash as well, but the front right hand bulb stays on. So its flashing on the dash but not from the outside

Thanks for the help all. I got it sorted out. The left side was a sketchy connection due to a bad crimp on the hot (white w/ blue) wire. The right side is a bad socket. It looks to have been replaced at some point. The wire coming in from the headlight switch (brown) is keeping the light on, so I just looped it back to ground FOR NOW. DON'T WORRY, I'LL REPLACE THE SOCKET AND FIX THE WIRING

I have a similar problem. With the lights off, all 4 turn signals work fine. With the lights on none of them flash. But the lights are fine. I suspected ground issue, and actually found a couple so I replaced all 4 sockets. I suspect something else, since my brake lights don't work, the hazards don't flash (or appear to work) at all, and the panel signals (green arrows) don't come on at all.
According the wiring digram the brake light go through the switch in column and the hazard flasher, but I don't see the panel lights on my diagram so I don't know where they are in the circut.
I suspect either the flasher, or the actual switch but was curious if any had any other ideas.
