When it’s cold out the window switches work fine. When the outside temperature gets to be about 70 none of the switches work. When I leave in the early AM they work, when I come home at night they don’t work. What could be causing this?

Anyone have any ideas?

Dirty contacts. If you're lucky, it's the fuses, replace them with ceramic/copper fuses. Otherwise, it's the switch contacts. The switches can be disassembled and cleaned, but it takes a fair amount of skill. Otherwise, replace them and be happy.
