alright my climate control is pretty ghetto right now. i have a seperate switch for my temp up and down and half my LED's dont work and i dont know why. since i removed and soldered them again? but anyways.... i see ppl selling climate controls that are perfectly good. my qeustion is are there upgrades to the system that ppl are doing? i am not talking about the LED's or anything i am talking about from a diff car or anything like that? i just wanted some backround before i go and get another one. mine is the 89+ climate control also if that matters at all.....
