I de iced my headlights and managed to break off the headlight washer unit, how do I replace this this? Is it easy to do?

Its pretty easy, I plan to do this job in about 4 weeks...any sooner and I'd write a little guide for you. Basically what I did when I last had to do this was to unbolt one side of the bumper then reach up and attach the hose to the back of the washer. After that I simply reattached the bumper and it all went back in. The problem is my washer jets have no clips so one of them fell off again.

Anyway...

1) remove the plastic bump strip trim, it needs a little tug and pops off. I used a flat bladed screw driver very careful with tape on the back to get it started.

2) unbolt bump behind this trim.

3) unscrew the inner wheel arch on that side.

4)the bumper should move enough that you can reach in and grab the washer hose, then poke your washer jet through the hole and reattach it.

5)reassemble.

Please note...thats only what I remember from doing it 18 months ago, I may be completely wrong! Its not a hard job though as long as you know lefty loosey righty tighty!
