Air conditioning only stays cold 1997 Lexus LS400

My air conditioner will not adjust off of it's coldest setting.  What could be the possible causes and fixes?  Thanks in advance

Check the AC for codes, One of the servos that control the doors might be bad.

The information is not enough. Did you adjust the number up but it not go up or Did the number go up but you never feel the heat?
