hie guys. i got an astra mk4 03 reg and on saturday i was pulled by the old bill in their unmarked vectra (ex road wars ) and they said one of my brake light was not working, i got two bulbs and tried them but still it wont work. this is the passenger rear brake light. so i took the unit thing(THE ITEM THAT HOLDS THE BULBS) and swapped it with the drivers side rear and it works, and the drivers side unit works when i connect it on the other side. ive changed the fuse and still wont work.
so where is the problem?
