holy crap what a pita! just got mine out to replace it breakin it all to hell in the process. clips holding the bottom half that needs to be replaced to the upper and you cant get to them. plus they sent me the wrong damn one so when I get the right one, any tips on assembly? I talkin about the housing that the actuator motor bolts to by tour right foot above the gas pedal, it has two flapper doors in the upper half and one in the lower. its a 97 k3500 with ac.
