Here we go !! does the right inside blinker light and the dash share the same ground and if so where the hell is it ? Thx

The physical and electrical parts of the dash changed drastically in 1990. Without knowing a year it's impossible to give accurate information.

That said, I do know that on the '80s dashes there are two grounds. The grounds for all the sensors is G104 on the side of the block above the oil filter. Everything else is grounded at G201, which is on the door hinge pillar.

Generally speaking a problem with a "blinker" on the cluster is either a burnt out bulb OR if it's a lights but does NOT flash issue that is an exterior bulb or bulb socket error. Not always but it's certainly the most common fault you would look for. If you had a lights and flashes but doesn't cancel then that's certainly something not related to grounds or conductivity.

What does the right blinker do?

One other way to troubleshoot this is to try the 4-way flasher. The turn signal and flasher circuits are mostly separate so sometimes this will help.

A lot of turn signal problems are caused by the filaments of the bulb shorting together inside the bulb.
