A/C control lost, keeps blowing hot air!!!

[rogerkiu]

Hi all! I really need all of you to help!

This morning I started my X, the A/C control did not show anything, just dead at all. No response when I pressed the buttons. Meanwhile, it keeps blowing hot air into the car through vents in footwell, and the air was getting hotter after engine warmed. I turned off the car and got the key out, it was still blowing heat air. No way to stop it. What is the problem? Is it the A/C climate control dead or something else goes wrong? Right now, I could not stop the heat blowing, so I just cut the battery power.

Roger,
The head units are, just like the rest of BMW electronics, junk and prone to failure. The good news is that they can be repaired if you have a good local electronic repair shop. The alternative is a new unit from the $tealer.
You could try unplugging it and replugging it again in case it might be just dirty contacts. Also check the fuse/s associated with the unit.
North Hollywood repair (check the web) have ads in the Roundel mag. all the time. Given your distance from them they MAY offer some advice other than send it to us but I don't know them so cannot say for sure.

Thanks Paul! I just bought a brand new control in eBay for US$400 including shipping. Is it a good deal?
