Temp door potentiometer open/short Code 19

Came across your vdo while searching for ambient temperature sensor. 1. My 2009 i20 Asta petrol ambient temperature is stuck at 26c while the ac is cooling but not as expected in LOwest cooling. Can you suggest what could be done to address it. 2. The left rear door window is not pulling down when rear passenger uses, but is working only from driver side door panel. Dunno if these two have any inter- relation. 3. While cleaning the car I saw a small blown out long bulb on the driver side door hinge. I ignored n threw the bulb. In retrospection I think I should hv taken a pic of that blown out bulb for narrowing down issue. Shared points 2 & 3 for easy understanding & diagnosis, if it helps.

Sir how to update the software version of thr trip computer??

Jese ac ka gas kya ese hi heater ka b gas hota hai?
