i am having trouble with my heater in my truck im not gettinn hot or cold air or anything for that matter to come out and i was wondering what it could be its getting way to cold to be going without a heater
when you turn it on is the fan blowing? Also make sure you have enough coolant in the engine. When the coolant gets low it drains from the heater core. Also check all your control cable that move the flaps inside the unit. That is what was wrong with mine. I just stuck it on defrost. check to see if your heater core has a leak or has been bypassed. As for the a/c, I'm not sure about that.
i found out what the problem was it was a fuse belive it or not it was blown so i jsut slap another one in there and it started working
