Inside Cabin temp cannot be controlled; outside temp sensor does not work

[mysaab2009]

Saab 2009 - 9-3 Turbo

Replaced the outside temp sensor - still does not work.
AC was not working at the same time; recharged with Freon;now AC works fine; but unable to find leak in sealed AC system
Heater cannot be controlled; blasts HOT although control set to min temp
Are they all related or is this a known issue with electronic module or coolant sensor?
Cannot use automobile if cabin inside cabin temp cannot be controlled!!

Carefully check wiring for outside sensor. Very common for it to get worn/damaged/corroded. Wiring goes to side where washer bottle is and is supported by under car splash shield.
