I have a 2001 Pontiac Montana with the following problem.

With ignition on both turn signals on the dashboard are always lit up.

When activated passenger side turn signals work fine front and back of vehicle and dash board signal blinks.

When activated driver side turn signals front, back of vehicle and dashboard light up but DO NOT blink.

When hazzard lights are activated both signals are lit on dashboard but do not blink and no hazzard light blink front or back of vehicle.

Please help

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Have the sockets, connections and shared electrical supplies and grounds checked under the actual operating conditions, using the matching wiring diagram.

On my 97, I discovered the socket(s) on the rear driver and passenger sides, burned out. The pins got hot, where the bulb(s) socket and melted it.
I was able to repair it but you may end up having to either have dealer replace, or go to salvage yard and find a replacement that works. Very poor design on GM's part in my opinion. But yes it is more than likely either bad bulb or bad sockets causing the problem.
Look carefully at the sockets. Took me no time to fix it but a long time playing with it to discover the problem. You wiggle the bulb(s) while it is flashing with the turn signal assembly out of the vehicle and you will discover the problem more than likely.

A 2001 Pontiac Montana had abnormal turn-indicator operation and inoperative hazard flashing. The owner said the bulbs had been checked. Another participant described damaged sockets on a different vehicle.

Reported outcome: The original owner did not report a repair.

The other participant's socket repair does not establish that this Montana has the same fault. No electrical measurements were supplied.
