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 stays on all time
fan speed button on the climate control stopped 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. :-).
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.
Not warming inside the car. Set at 80 degrees! Even after driving 10-15 minutes
intermittent AC
Ace comes on blows cold air then starts blowing regular air. Ace is charge. no leaks
Fan will run when car is off climate control fan
Air just blows ambient temperature
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.
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
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.
The AC blows hot air. I can manually set to the coldest setting with the fan on high but it doesn't matter....it doesn't get cold. There are times when running for about 10-15 mins it will get slightly 'cool', but it is never even to even come close to cooling the entire cabin.
For extremely cold days - less than 32 F - the heating struggles or kicks out.
sometimes the climate control will not shut off and I have to disconnect the battery and wait few minutes and connect it back , It remains off as long you don't try to turned it on.
Air stopped working put pressure gage on the a/c and it says it could have mechanical issues....
