air conditioner didnt work in the front or rear and blew out hot air so i had to have the compressor rebuilt because it was leaking out the coolant, and i also had to have the the coolant line replaced that runs to the rear a/c compressor because this vehicle is rusting really bad underneath and the line was rusted through. This fixed the front a/c but the rear still blows out hot air. Also noticed once it got cold outside that the rear heater doesnt even get warm. It has something to do with 2 different switches in the rear that change it from air to heat, but ive never had it fixed because i havent had the money, so i have to deal with sweating in the summer and freezing in the winter because the front a/c and heat isnt enough to cool down or heat up the entire van.
