Download This guide is based on a car with a manual hood mechanism. There are minor differences on a car with a powered roof not covered by the guide. It might be advisable to turn the T shaped screw on the pump to allow the hood to be raised and lowered manually. This will allow the fitter to judge the tightness of the hood more easily. Please bear in mind that fitting takes a fully experienced fitter several hours & is not a job to be undertaken lightly. Remove the wiring to the heated rear window and then remove the window. To do this curl the lip of the window’s rubber seal away from the frame in one of the top corners and push against the glass in that corner at the same time. Ease the seal lip away from the frame all the way along the top of the window whilst pressing against the glass. Push it out just so far so that you can get outside the car and pull the window the rest of the way out. Or get a mate to catch it if you like!
