Climate Control unit problem (AC and heat does not turn on)
I have a 2004 BMW 330ci with about 70k miles. The AC was running fine two days ago, but it stopped working yesterday (90F and humid day). I pressed the fan button to turn on the AC but the climate control unit does not respond (i.e. temperature and fan speed LEDs do not turn on). I checked all the fuses, and they are all fine. It appears the climate control unit went bad, but I want to make sure since the part costs ~$500 and non-refundabe. Anybody have a similar problem to this?
