My current fan (Drivers Side) has a portion missing......not good......can't run the A/C or it makes an awful racket. Bought the new fan with motor assembly and it has 3 studs and 2 plugs. Can't be that hard. How do I get the old one out? What do I have to remove to get to it? I am guessing the belly pan to start. HELP !!! Have to DIY as I cant afford to take to dealership or mechanic......Thanks !!!!
