Chevrolet G30 turn signals malfunctioning, only back passenger signal operational on Chevrolet G30

Some Chevrolet G30 owners report experiencing turn signal issues, specifically where only the back passenger signal is operational. Common causes include burnt-out bulbs in non-operational signals, which should be checked for damage or burnout. Additionally, a faulty flasher relay may lead to malfunctioning lights or a lack of response when the turn signal lever is activated. Wiring issues may also be a factor, so inspecting the wiring for visible damage is advisable. Defective stalk switches could contribute to the problem as well, necessitating a check for any visible damage or malfunction. Furthermore, some owners find that issues with the front turn signals can impact the rear signals, making it important to ensure that the front signals are functioning correctly. Addressing these potential causes can help resolve the turn signal malfunction effectively.
