The filter is under a elongated triangular cover at the base of the windsield.. I think it has six phillips screws and a red and green hoses going to it. I would gently remove the hoses and the screws, there is also a sender in the side of it near the drivers side. It might help to lift the sealing gasket, the filter sits below that cover and is also a sort of triangular thing. The blower regulator is mounted on the blower housing, and uses a dielectric paste under it. You should be able to order a filter and regulator form Fast Lane right here, at a much better price than your dealer. The regulator is in the ground side and the hot side is not fused. There are two versions one with a carbon coating, the other not. There is a third one if you have the electronic filter with a switch on the dash, to change that one the windshield wiper pan the wiper arms and the transmission needs to come out. It can be done but is incolved!
