The Camaro Club (UK)

Ok, this is odd... I have a '94 Z28 that has an intermittent problem with the right turn indicator. When you move the stalk to turn right the light illuminates but doesn't flash. The weird part is that it starts working again if you open and close the passenger door! This has happened about 8 times now in the last couple of weeks but works fine for the most part.
Has anyone encountered this before or can maybe explain what the courtesy light has to do with the bloody indicator? cheers...

Dodgy earth try by the back lights or if its butchered to meet uk mot standards anywhere round that earth wiring.

Thanks for that, i'll try to have a look at it tomorrow after work
