xc90 ac fan in auto not going to high speed then coming down slowly
AC works fine in man mode, put it in auto mode and fan speed goes to the lowest setting and cool air comes out, you can manually turn fan up, works great. go back to auto mode and fan speed is at lowest setting, turn controls to 60 in auto mode, and fan goes to high. All my other volvo's, fan comes on high on hot days then gradually comes down to lower fan speed., once car is cooled off inside. Help
