Kind of odd thing going on...the first night i got in this 2009 int. prostar the sleeper ac blew cold air all night...when i woke up i was sweating because the heat came on during the night and now that is all that works back there...am in az with a broke down reefer having to get motel room bcause its 110 deg outside and 95 degrees in sleeper...any ideas? Ive messed with the slpr temp and slpr fan dash controls but that does nothing to change the temp ...the ac up front works ok...thnx
