Why does my volovo have an odor when the air conditioning is on?
I purchased my volvo preowned and I noticed it has a sour smell which is stronger when
first comes on and then subsides. I do not know about heat since I have only had it for 3
months. No evidence that it was ever in a flood or other maintenance problems.
Purchased through a reputable online dealer.
Sounds like the A/C condensation line is clogged up. Line is at the bottom of the evaporator case on the fire wall of the vehicle only can get to it from underneath the vehicle. Use air to blow out line.
Change the cabin air filter if equipped. It possibly has mold on the evaporator and needs to be cleaned. See the Volvo dealer for that.
