I will be crossing the Andes in June or July, which is winter and I heard buses can be exciting but passes might be closed and such. What are the best routes and where can I get info on passes?
Well my flatmate and I did that trip July last year.
We went through Túnel del Cristo Redentor/Paso Libertadores which was amazing. It goes from Mendoza, Argentina to Santiago, Chile down a jacob's ladder.
You will have to have very good luck to travel that pass in winter though. Other passes go much further north or much further south and take an extra 12 hours or so from memory.
The websites to find information on the passes across the Andes are:

And don't forget the bus stations
You can go in to the bus station in Mendoza (and probably other cities/towns) every day and check the status of the passes.
The company we took over the Andes was called CATA Internacional but there are plenty others who do the trip. over 10 years ago
I crossed from Bariloche to Osorno in the middle of winter 05
I had to wait for a window when the road was open, but it was the most spectacular bus trip I've ever taken!
