Zafira brake lights issue

AutoGlasgow · Feb 23, 2015

Hi guys,

Issue is this:
Zafira A (03 plate), left and right brake lights not functioning, but tailgate brake light working fine. Fuse fine and bulbs tested and working fine.

Any ideas to get me started on this?

Any help would be great.

Appreciate it. Thanks.

corrosion or bad contacts on light clusters. poss. the earthing side.

Try Googling it, too much info to copy'n'paste. It may be a case of "Houston you've got a problem."

Thanks telectrix.

There was a little corrosion on the contacts on the right side only, which I cleaned up, but didn't fix anything ...

time to get the multimeter out and see what voltage you get and where.

Do all the other lamps ( indicators, tail lights, etc ) in the rear clusters work ok. Just looked at the Haynes manual wiring diagram and the only thing that I can see would be an earth fault on the earthing connection in the LH rear panel but this would probably cause other lighting faults on the rear of the vehicle. The H/L light earths on two points which is probably why it is not affected

Thanks UNG. Appreciate you looking that up.

No, all the other lights on both rear clusters are working fine ...
