HVAC temperature differences
I have a 2013 Laredo X (auto climate control) with 20k miles. On a couple occasions I've noticed my driver's side is at a hotter temperature than the passenger side. As an example, this morning the driver's side was blowing out nice and toasty. On the passenger side, the vents were noticeably cooler. Not ice cold, but cooler. I was able to cycle through the vents without issue (floor, face, defrost), but the air temperature was noticeably different.
I had been driving for about an hour. The last time this happened, it had only been running for 15 minutes.
Any thoughts on what might cause this?
