Customer reply replied 3 years ago
No left signals or left flasher Works intermittently Trailer connections were corroded so were disconnected no change. Leaning towards multi function switch?
Customer reply replied 3 years ago
I can get them to work sometimes by operating lever till they come on. All flashers work when left signal is working. Sometimes all is fine next time not

Are you thinking
Customer reply replied 3 years ago
Most of the time when I get it blinking it quits when I put it in the lock position. Thinking it's the switch
Chevy Mechanic: Dave Nova, Chevrolet Technician replied 3 years ago
Sorry for the delayed response. Most of the time the problem is a bad ground connection at the rear taillight connector. Remove the left rear taillight and disconnect the electrical connector. Look for discolored terminals or even melted plastic on the connector body. Let me know what you find.
