First , can anybody tell me wut i need to replace or fix with my AC... The air works great except the fact it only blows through the defrost vents... now my mom, her car is the opposite, well kind of hers only blows fully on or off... is it just the dials? im clue less here.... next thing my car every time I go to start it, it takes 2 or 3 good turns of the ignition to start regarless if the car is hot or cold, wtf gives??? plus u can smell fuel as well.. and once in a while white smoke, but not a heavy smoke, just enough to notice... I got more questions ... Its only happened maybe three or four times, but all within the past few weeks.. while driving my RPM's start to jump all over the f-ing place, and wont accelerate 4 snit...car eventually stall's out, then all u can here is continuous clicking inside passenger front side fender, anything to be alarmed with, and is it pricey? This is just a money pit I tell u wut, Thanks for any input, sorry about the novel.... plz help... Also about how much to rebuild a rear end? Thanks
