this was covered under warranty.... so went to the dealership thinking p*** easy job, new unit, bish bash bosh.... noooooo not that easy mr!
1 - take spoiler off
2 - replace unit
3 - glue it back on
butttt....
if the spoiler snaps.... then you need a new spoiler, then add paint, then add the labour for that!
luckily mine didnt snap! so just got the strip replaced! but worry thing was i had vinyl on the roof part and they said that it might ruin it! - but they did a awesome job!
heres the scary thing...
