Strange brake light issue...

[greg71]

Hi guys,

I recently had the rear driver side brake light issue, I fixed this by opening the turning light switch and cleaning the contacts.

Since then, my driver side brake light is not working anymore....the passenger side brake light is working as it should but nothing on the driver side...

Hazard lights are working perfectly too.

Could you please tell me what to do ?

Thanks in advance!

My side markers quit working too. I took the lenses off and cleaned the sockets with sand paper and spray electrical cleaner. Now you could see them from an airplane.

thanks for your response, actually my side markers are working great, this is a brake light issue. cheers

There is a good chance that when you took apart your turn signal switch, the rocker for the brake lights on the driver's side was displaced.

On the image above, it is the rocker at the top.

When you use your turn signal, the switch pushes the rocker away from the contact so that the rear light is part of the turn signal circuit instead of the brake light circuit. If the rocker does not resume contact, the light will not illuminate with the brakes.

I hope this helps.
