For some reason all of suddon i have no heat. It blows but the control unit (fan speed) doesnt work. IE it doesnt blow more air when on 4 then on 1 its all the same. But i also dont get any heat does anyone have a solution to this problem or know what it could possible be. Its not over heating or anything like that its stays at the normal driving temp. Thanks for the help.

 

I don't work on many Passports (thank God).. But it sounds like your blower resistor is burnt out. As to where it's located, usually by the blower motor in one of the air ducts.
