Climate control problem

[LSXHP]

My GTP is a 99, problem I'm having is the climate control box (Dual climate control). When it displays the ext temp it keeps reading wrong. It will start at say 50* and slowly count up to the actual outside temp 1 degree at a time then begin to count down all the way to -39* and sometimes just stay there at which point its really say 90* out and my ac pump shuts off because it thinks its so cold out. This problem is intermminent but becoming much more common almost a daily thing lately. Any ideas on whats going on? I'm guessing either the climate control box itself is bad or where is the sensor that tells it what the outside temp is located at??

On a side note my heated seat also intermintently quits working and dont seem to work much at all anymore and my HUD will get dim sometimes and then go dim then bright dim to bright over and over, could these all be related to a single problem?

that is the sure tale sign that the temp sensor is on its last leg.
This happened to be on my 2k replaced sensor and all was good
