have had same trouble with fan speed control not responding or changing force of blower on its own - told I need new climate control module and software upgrade for approximately $1800 in part(s) and labor. Haven't done it yet as I as trying to find out if way of getting software upgrade without replacing climate control module to see if that fixes it (if you can even get such an upgrade without getting a new part/module??).
blower motor stop working
heat will not engage. blowers work AC seems to work. No heat comes from vents. but the seats get hot. Also, oil leak from AWD. Two out of five problems on one car, this is not good
fan speed button on the climate control stopped working
AC goes from blowing cold air to regular air then recently does not blow any air at all
the climate control fan, i can not stop.
Fan will run when car is off climate control fan
Ace comes on blows cold air then starts blowing regular air. Ace is charge. no leaks
air does not get cold. sometimes blows warm. Had cooling system checked and they said I need a new climate control module which in 800 plus labor and programming
After driving 2 hours on highway in very hot day 100+ F.
Blower speed control stop working. Blower start working in two stages off or full speed.
During couple hours stop, after ignition off, blower did not stop and was working all time (2 hours).
While next 1 hour drive temperature control stop working. Was stuck on cold. AC on/off button was working.
2016 XC90 Volvo has no heat. I reset the center console and it still will not come back on. The AC and Blowers are working but still No Heat and it is snowing here. :-).
Not warming inside the car. Set at 80 degrees! Even after driving 10-15 minutes
Fan cuts on when the Volvo XC 90 is turned off. Not sure of precisely the scenario in terms of how the system was set prior to turning off the car, but this is clearly a bug somewhere.
I have had the system recharged and then took car back for them to check again, they could not duplicate the problem.. so did nothing. Happening again now and will return to dealer this evening.
No solution -
Blower motor stopped working. Still get air thru ducts if car is moving and recirc is off. Hoping it's a software thing but not holding my breath. This Volvo was purchased overseas with the military purchase program and we've had multiple problems (The mirror computer was completely replaced TWICE within months of purchase, etc). This is the first major problem out of warranty.
Blower and A/C work Great. NOOOOO HEAT
Ac stops at times and comes back randomly
