Toyota Repair: a/c, ac module, air pop

Question
hi i have toyots tercel 95 model its a/c is working and cooling also but after 5 minutes it stop working and send warm air wht shuld i do

Answer
I think first you need check the problem is the AC cooling system or the mode door.
when the system blowing warm air, pop the hood and put your hand on low pressure pipe within 5 minssee see if it still cool or not. if it become warm you have the problem of the AC system, if it the pipe still cool, the problem should be mode door of the AC module, because it not holding at the position of the cooling mode.
