So if you're following me, I just replied to Megan this morningregarding her AC issue. I explained to her how the compressor supplies both front and rear evaporators and a quick explanation of the actuators. I mentioned that I was having an intermittent issue with my actuators, but hadn't checked them yet.
Here's the story: About a month ago, I started car and got about 10 secs of a squeal coming from the dash, couldn't tell exactly where. After that, the passenger side AC doesn't get cold. It gets "cool," but not as cold as the drivers side. A day or two later, it's OK again. Then it's bad again. So it's been off and on, with more off than on, ever since. As I told Megan, I thought it might be the passenger side temperature actuator, but I hadn't checked it yet. So now I've shamed myself into checking it. (I did pull the fuse and let it recalibrate a week or so ago, but that didn't change anything.)
So this afternoon, I observed the mode actuator on the passenger side move full range while swapping from vent to floor to bilevel to defrost and I observed the recirc actuator move full range for outside air and recirc. I observed the passenger side temperature actuator move full range from hot to cold, but it never gets as cold at the driver side. I couldn't understand why the passenger side wouldn't get cold if the actuator is moving full range, so even though it's a PITA, I pulled the actuator and verified that I could physically move the damper myself. I can actually hear and feel the damper go closed in the cold position, but still get only "cool" air.
So I'm wondering how in the heck can the damper be moving fully to the cold position, but I'm only getting cool air, not cold air?
Anybody have any thoughts?
