Hi fellow VW owners!

New person here..glad to be part of the forums.

I have a 1997 VW Golf and the when i use my turn signals:

Day: They work fine front and back EXCEPT when I brake. The turn signals stop blinking

Night: When i use turn signals braking or not, the rear brake lights (left, top center back and right) flash at same time...regardless using left or right signal. When i apply the brakes..they stop blinking.

Any ideas what could be causing this? i changed bulbs but that has not helped.

Thank you for all your help! I don't want to get rear ended or a ticket because the turn signals don't work when i brake.
