2007 S80 heater not working

Post by Wetlander » Mon Oct 28, 2019 6:35 pm

I'm driving a 2007 S80, newer generation with 128K miles. I'm not getting any heat from drivers side vents, and only a very, very slight amount of heat from passenger side vents. Same for windshield defroster. Blower fan seems to work fine and AC works very well. Have not witnessed any coolant leaking onto floor and no coolant smell in cabin when asking for heat and blower is on. Wondering if I should be looking at thermostat, heater core, damper motors, or something else? This is a new car for me, and it's my first Volvo, but I'm interested in trying to figure things out, so any help is much appreciated. Cheers!
