Question about 1992 Buick Regal
Hello, I have a 1998 Buick Regal GS, left front signal does not flash. Left rear works just fine, right side front and rear also work just fine.
side marker does come on when left signal is applied. I have replaced the signal stat, cleaned all wiring contacts. also left indicator does not flash.
When this problem started the signal worked fine until the car was warmed up All grounds have been cleaned.
I dealt with a similar problem on an 01 Alero (very similar car) and found that the wire that grounds the signal filament of the bulb was broken inside the harness. I tapped into it and grounded it to the chassis and resolved the problem. It's no guarantee but if you have a multimeter, check each wire's continuity to ground as well as the impedance between each of the wires on the harness, on both front signals (for comparison purposes), and it'll show you if you have a problem such as the one I dealt with.
