I recently had my AC compressor, expansion valve and receiver/dryer
replaced. I got the parts from the Bus Depot (great quality parts!)and had a
local Seattle shop, European Motors, install them, flush out the system and
fill with R-12, all total about $1000, ouch! I went with R-12 after reading
lots of info on R-12, 134a, Freeze 12 and others. Fortunately now the system
works great! I've noticed that it really does matter where you aim the
vents. It's not as good as my BMW but the AC in it is amazing. I've read
lots of comments on the AC on the Vanagon not being that great but with
everything working properly it works fine although I do notice the power
loss when it kicks on now but I can live with that.
I also had the windows tinted for about $300 with metalized film and I'm
quite pleased with the results. I went with 30% film, not too dark. It's not
as hot when parked or driving in the sun.
