I have been having a problem with the a/c in this car. It will work for 3-5 min very well then cut off and blow only hot air. Today i was waiting on someone and trying to get a dust ball out of the 3 slots above the temp control and noticed a wire in there was broken. im not sure if i broke it or if it has been broken. Would this cause the problem I have been having or have i created another problem in it self? Also could i just solder the wires back together or should i replace it some how?
