Blinker issue-71 Duster A01

No. You have two "unrelated" problems.

"How this works" is there is a left front and right front wires coming out of the turn signal switch. These branch off and feed up to the indicators on the cluster. They also feed out through the bulkhead connector to the front TS bulbs, and branch off and feed the fender indicators.

One thing to find out is if you do or did have the gas mileage gizmo, I'll think of it here, "milage master" or some nonsense. had a relay and vacuum switch that hooked to the left fender indicator to help remind you to "stay off" the gas

Here we go, "Fuel Pacer"
