Hi as a complete Ford Focus fan i am glad to join this forum, now i can clean and polish a car no probs, but when it comes to technical matters i am useless, here is my problem,

bought a 2nd hand F.F Ghia 1.6 3 days ago from a dealer, trouble was he wasnt a dealer with a yard he was a home dealer, never bought a second hand car so thats where it all begins, car looks good , anyway on trying the A/C in the hot weather it doesnt work, fan works on number 4 only 1/2/3 are not working or blowing air at all, took car to halfords today thought it might need topping up after a 3 hour wait he told me to bring it back on the 11th June when they will have an EXPERT there, i was surprised as i thought they would tell me what was wrong, he said i could be looking at a bill between 170 and 250 pounds for a complete diagnostic check and service.............any ideas would be appreciated....
