No heat on passenger side vents, mild heat middle left vent and full heat driver vent. Checked DTC indicators and saw a DTC 5 (problem in mode control linkage, doors, or motor circuit). Noticed that the passenger side blend door actuator wasn’t flipping when changing temperatures so I tried plugging in a new blend door actuator, but the motor wouldn’t flip when I changed temperature. Made me think it was a fuse issue, so I swapped out #36 fuse but still no luck. Though I’m honestly not sure if that was even the right fuse. Didn’t have tools to test voltage so could be that the cord just doesn’t have power going to the blend door actuator. Previously had A/C issues necessitating a compressor replacement and a few other items, but I don’t think it’s related to heat issue as the heat issue seemed to exist prior. Any thoughts on what could be causing this or what else to check?
