I do believe under the hood on the passanger side all the way in the back right to the right of the hood hinge. you should see two hoses going into a "box" with a blower motor and all that good stuff !
Yes it is behind the dash in the box and i think you can get to it though the inside panel down on the floor on the pass. seat but i havent done this one in a while so i cant really remeber. but take down the glove box cover and look behind that 1st!
