My Edge has dual climate control, and has an issue lately where the driver side would pump out hot air regardless of what temp I set it to. I found a video on how to reset it, and it takes a couple times to get it. But lately it's happening more often.
I'm thinking the blend door actuator is messed up. Would that be the correct assumption?
Also, a couple weeks ago, noticed a low whirr from behind glove box and doesn't go away at any speed. Is it something caught in the fan, or something else?
