LHS washers
LHS washers
My LH windscreen washer doesn’t put out any washer fluid so I started to try and see if it was blocked and then noticed the LH headlight washer also doesn’t work. Are they fused separately to the RHS washers and is the LH headlight washer linked to the LH windscreen washer?

IIRC, the windscreen and headlight washers have separate pumps.
The headlight washers don’t squirt every time the windscreen washers do. They only squirt once every X times for the windscreen squirt. (I forget what X is, it’s probably in the owner’s manual.)
Check to see if washer fluid appears under the car when you’ve tried the windscreen washers a few times. There is one hose from the windscreen washer pump that goes up to under cowling at the base of the windscreen, right about at the midpoint, and connects to a plastic T fitting to split the flow to the left and right sides. I, and others, have had one of the hoses come off the T, resulting in no flow to that side. So if you get washer fluid under the car, you probably have same issue, and just need to reconnect the hose (a little bit of a pain to get to). I put little hose clamps (from a drip irrigation system) on the hoses on the T to prevent it happening again.

Thanks, I did have some experience with the T piece but no leaks so not sure why fluid doesn’t come out of the washer jet. Does it unscrew? It has a slot on the actual plastic jet but scared it may just disintegrate!

He found water filled bags all around the reservoir, but goes through the components well. But I think his issue was both wipers. Worth a watch.

Get the T piece under the windscreen cowl and take the hoses off and turn on the washer jets and see what happens.. there's hoses going from the headlights under the front radiator cowl which could have got dislodged or your pumps could be wrecked or blocked.
I would see what the T piece is doing first as it's the easiest to access
