A few weeks ago the light stalk stuck and would not flash or operate main beam, other lights ok, it just would not pull towards me. Decided I could live with it until Christmas was out of the way.

Few days later, started car, switched lights on, only parking lights working. Turned the stalk on, off, up, down etc several times, switched ignition off, restarted, all lights ok - including main beam.

Driving last night, the blue main beam light was glowing dimly when on dip. Today, the blue light is fully illuminated when the lights are switched on, in 1st or 2nd position, but the only front light operating is the passenger side parking light, and the stalk moves freely but will not flash. All rear lights, indicators and foglights are fine.

I guess the problem is the stalk/switch and not a fuse or relay (the accessory relay was replaced recently). How straightforward is it to replace the stalk?
 
The main beam indicator light is normally fully illuminated when a bulb has blown, I'm having the same problem as you at the moment and mine was due to the earth not having a good connection on my near side bulb. Might be worth a try?

Thanks, I didn't know the main beam indicator did that!

I should be able to change bulbs today, and even swap out the relay, but I'm not confident of sourcing a new stalk locally today. Plenty from broken cars on fleabay but not with fitting instructions.
 
I had something similarish the other night - blue main beam light quite dim with lights on dip - passenger side AOK, drivers side as if dimdip bulb had blown and was running on sides only.

Stopped, popped bonnet and wiggled the connector on back of light housing 'home' as it seemed loose - cue some strange whirring noise, and hey presto light back to how it should be!
 
Had a guy at work look at it and the driver's side bulb mounting has scorch marks and a melted area. Couldn't get a new bulb into the mounting. Abandoned theory about the stalk.
