I assure you, it comes out the top..... I just don`t remember how.... I`d consider going out and trying it, but it`s not a job you want to do unless you have to.....
It may have been out the back, between the motor and the firewall.... on the passenger side... keep trying it at different angles, eventually it should it pop out....
I can`t remember if it came out pully up, pully down, pully sideways...... but it did come out, and the new one went in.
