Hey guys it seems that my auto climate control unit is broken. sometimes the defroster wont work and i been threw 2 of them. the 2nd one one was used. when the froster dont work. i have to turn it off and turn it back on for it to for it to defrost. lol so ghetto but yeah. also. and the heat only turns hot when i set it to HI and its the hottest setting if i turn it to 82 or 80 it turns cold. like i cant get to a nice warm tempture. so do you guys think its broken? do you guys know how to fix it ? or if i can it rebuild? or you guys know anyone that can rebuild these? or i would have to buy a new one which is very expensive -_- let me know thank you.
