I've been dealing with a lack of air conditioning in the van this summer because we really haven't needed it. Honestly, I've put under 6k miles on it in the past year. Got fed up, paid for a recharge bottle of Freon from AutoZone and followed the directions a couple weeks ago. It helped slightly, but it wasn't getting icy cold. The compressor was going on and off, so it wasn't a serious issue for sure. I threw a set of real refrigerant gauges on it today and added another partial can of Freon. Damn, that was it! Me 'n da mutts are gonna be happy cool campers going out east now.
