Has anyone had this AC problem???
 

i just bought a 94 fd 3 weeks ago and i have had a stroke of bad luck. on monday of this week, i took the car to get the oil changed and the mechanic that changed my oil ran into another car going from the back of the shop to the customer parking lot. the damage isn't that bad and the shop is going to pay the $2200 worth of damage.

so anyway, i turned my ac up to level four today and something happened..... when i put it back down on level one, two or three, the fan no longer blew air. it only blows air when it is on level four and the ac light goes off, hence no cold air. when it is on level one through three, the ac light is on, but there is no air. any suggestions??
