Chevrolet Monte Carlo turn signal works in park but fails when in gear on Chevrolet Monte Carlo

Some Chevrolet Monte Carlo owners report experiencing issues with their turn signals, specifically that they work while in park but fail when the vehicle is in gear. This problem may stem from a faulty connection between the dash lamp and the front lamp socket, as indicated by the left-hand dash lamp functioning in park but not in gear. Additionally, if the driver side turn signal operates correctly while the passenger side does not blink when in gear, it could signal a malfunction in the passenger side front lighting system. Furthermore, if all three signals on the left side fail to flash when in gear, it may suggest a burnt-out bulb or a bad ground connection on that side. To address these concerns, owners are advised to check the connections between the dash lamp and front lamp socket, inspect the passenger side front lighting system for issues, and verify the bulbs and connections on the left side for any faults.
