Toyota Avensis T270, D4D, broken climate control, 2008 to 2015.

My climate control on the left side is not working at all and on the driver side dose work, but it is not stable and jumps to different temperatures on its own when manually trying to adjust, so i took the climate control unit apart in the hope of at least stopping the Irrational movements of the driver side control and hopefully fix the passenger side, but the passenger side is totally broke and Fortunately I managed to fix the control on the driver side and works fine now after cleaning the Electrical contacts inside the unit, it’s an easy job and dose work on fixing control that acts unstable and hard to control, but thankfully one side can work the unit and I’ll be happy enough to keep the unit as is and not replace at a cost to me, but if your unit works both sides and is jumping all over the place follow my steps and will fix it from Erratic movements.
