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?

Sync button was pressed, they were both at 81F. It was single digits today here in lovely Michigan.

Once again single digits and 81F on both screens. I started feeling a cold draft so I changed from defrost/foot to face vents. Both passenger side vents were toasty warm. The passenger side center vent was lukewarm while the outer vent was cool. Turning the temperature up to 83F on the passenger side warmed the air up immediately.

Try sitting in the passenger seat and see if it changes.
If there was a passenger, never mind.
