I did the power windows centre and the rears.. I did have some trouble they are very hard too me.. When i did the centre power windows it came out pretty good, But the rear switches are small and a huge pain in the bum, They took me forever to get right, And i almost broke them both or burnt them... I in the end had to replace one switch and it's green i broke my last LED

.. That's how hard i felt it was to get one in my fat fingers just wouldn't get in easy.
But it works once in...
So just too get the trip computer climate control display mode switch centre power windows and one single rear power window switch, I went through 2 climate controls and one rear power window switch..
But i didn't get confidence even from my mistakes.. The trip computer is maybe the easiest one too do once you get it out of the dash.
Like everything we try sometimes we stuff up but once we stuff up we learn more from that and we don't do it again

I'm sure you will do fine and if you troubled just pop into the led thread and ask away plenty too help you out.
It's alright if i see one drip they will need to replace the whole screen

Life time warranty.. I just need wipers now..
Mine are the same a touch slow.. Maybe they arms can be sprayed with wd40 up in the door?, Or maybe the seals where the window goes up and down is stiffer and older and rubs hard against it stopping it from moving faster?..
New screen..
