Heat From Only Side

[coopns]

11 Volvo...newish to me. The windshield heat only comes out of left side, other side blows cold.

Any thoughts?

blend door/actuator somewhere in the system?

does it have dual climate control?

That does sound like a blend door actuator problem. Had that issue in several cars and the placement is usually less than ideal unfortunately.

Another vote for a blend door actuator. Are you getting the telltale blend door clicking sound when changing heating modes?

The blend door is easily located. Get in the most awkward position you can up under the dash, look for a small module held on with 2 screws that there is no room to get a wrench on and a 3rd screw you can't see. If it has a wiring connector with no slack and no room to get your fingers on it- Bingo. That's it.

Easier to just remove the front clip
