I have an S15 SR swapped zenki with working A/C, and after a 45 minute drive or so the A/C freezes over and on speed 4 it feels like no air is coming out at all out of the dash vents. I'm certain that the drain tube is unclogged because when I park there's always water on the floor, but after driving for an hour I can pick up little icicles off of the blower unit behind the glove box. I tried keeping the A/C button off and going to full heat and it still does it (no heater lines hooked up), so the only fix is to keep the A/C off for 15 minutes and turn back it on.
