Turn Signal - need help Options

[young55961]

Hi there,


My left and right turn signals won’t flash when the headlights or parking lights are on. The turn signal switch works even when the key is off. My turn signal switch is very worn out. The high beams only work occasionally, and the return spring is missing.

I am getting a new switch, but I’m wondering if that is the issue, or if there could be a wiring problem causing the turn signals to stop flashing when the headlights are on.

Tks.

Kinda went through a similar situation; turned out there TS had gone bad. Wasn’t easy to figure out until the switch was off and I could test the circuits to the two circuits: turn signals and parking lights.
The grey wire in the center is parking light input; the black wire/green/white wire is the turn signal inputs,
On either side of each input are left and right outputs.
A good switch will show continuity between the inputs and outputs; so, connect he MM to one of the inputs and a left or right output. Move the turn signal switch and verify continuity; twice for the turn signals and twice for the parking lights.
