If you take your foot out of the roof you could sort both! I normally put my foot in my mouth as you can tell.
Firstly welcome to the forum - someone will be along soon to suggest you add some pictures of your Zed so try to do that soon. A lot of members move the roof motor to the boot because they often soaking wet and fail. If you search for roof motor moved you will find loads of info.
Another member might post or PM you the name of someone local who can help but have a go with the search.
