Need help with interior temp sensor

Can anyone tell me how to change the interior temp sensor on a 97 S320. I have no heat and I used directions found on a forum to read the codes from my climate control. Code 01=LO which tells me that the interior temp sensor is either shorted out or just failed. I have no idea where to find that sensor or how to replace it. Can someone help me with that. Oh yea and it would also be helpful to know where I can get one too.

Thanks

Well, I did not get any responses to this inquiry, but I did some research in this forum and found out that the interior temperature sensor is in the overhead unit that includes the front cabin light. After removing the cover I found the electrical connector for this device to be loose. I plugged it in and it now reads normally. That is just dumb luck. I still don't have any heat though and I am now trying to diagnose the duo valve. if anyone has disgnostic procedures for that valve please post them here.
