hi , i need help, i was absent for 6months and when back, the battery need to be remplaced for my 2007 v8 sport xc90. after i change the battery , i have problem with ac , it was very hot in the driver side and very cold in the passenger side.
i dont think it is a big problem may be need to reset somethink after changing the battery.
any suggestion ,
thank you

 

Probably not the battery but the thermal sensor. My car occasionally does crazy things with the AC. Sometimes the temperature reading drops to sub zero. Sometimes the two vents blow hot and cold airs at the same time at the same temperature setting.
