I have 05 Caravan, 4 cyl, 115k. Runs fine (just got back from a 2000 mile trip) that seems to have a quirk or something with the AC.
When I have the AC on and stop at a light, it feels like it hesitates several times. I almost think it’ll stall (never has). I usually end up turning off the AC while we’re at the light, and start it back up when I accelerate. When the AC is off, there is no hesitation. Also, If I put it in park, and we have the AC on, no problem. I rarely, if ever, have the recirculation going.
One thing of note: I usually wait until I’m out of our neighborhood and on the main street before turning it on. That means the windows are down until I turn it on. When I do, occasionally I hear a sound that best can be described as similar to the sound of loosening a tight lug nut. Still, as long as I’m driving, there is no hesitation and it cools fine.
