So yesterday my a/c temperature knob suddenly got much easier to turn and was stuck on hot no matter what position I moved it in. I'm pretty sure that my problem is the little electronic switch/regulator broke. I usually fix things myself and this will be no big deal.. But where do I find this part? I tried ebay and a few auto part "stores" online.. but no luck so far. So if you have any idea where I can find this it would be greatly appreciated.. or if you think there may be a different cause to this problem let me know. Thanks!
