Hello all. I知 new to forums but seeking some help. I have a 2009 Volvo S80 t6 awd. I was having an issue with no heat. Originally the heat/AC would cut on randomly. Then it stoped working completely.

I went ahead and replaced the the blower motor and also the blower regulator. I also installed a new cabin filter. After completing everything I知 still left with no heat. I looked to see if the blower motor is working and it is. It痴 spinning pretty fast. You can feel very very light air coming out of the vents. At this point I知 stuck. Can anyone please help

also I知 not able to check the blower regulator relay as I am not able to access the lower part of the fuse box. I知 left thinking it痴 either the relay or the climate control. Thanks for your time
