Ok I was on my way to work this morning and I went to switch to high beam but I used the wrong/left stalk. I found out if you push it away from you it gives one wipe of the wipers with no squirt of washer fluid.
I find it takes about 10 minutes to get used to them being on the Mk1 side (right) but when I get back into my Mk2 or Focus it takes weeks to get used to it being on the left again. I guess indicators on the right are just more natural (for me anyway).
