I have a problem with a 2000 Boxster-S, when you put the main beam on it only comes on with a very low intensity on the NS (the bulb works just very dim) and if you indicate with main beam on the main beam flashes with the indicator... The OS works fine!

Tried several bulbs and cleaned up all contacts for the light, any ideas?

Im thinking the switch on the steering column, but that would effect both headlights surely?
