help !!! i recently purchased a cherokee 00,a/c was not working no air would blow at all.after a couple of weeks i checked the resistor before i purchased the a/c blower and it worked fine,now i have replaced the blower and now it blows air it feels cold and all but the vents wont blow much air its very weak,however i can hear the blower working in all levels but not much air blows out .Ive noticed that whenever it blows like this the condensor starts "frosting" over and there is an excessive amount of condensation that starts dripping any ideas were to start ?
