    Hey guys my name is Robert Anderson and I just joined. I have a 2005 silverado with dual electric climate control. I have the temp set to 90 and it only blows cold air on both sides. It has done this a couple times before but it only lasted a couple minutes. And now its just stuck for good. Ive noticed that sometimes if i get on it hard it starts to work normal. Any help would be great!!

    first check the freon level or that the compressor turns on, when you switch the heater on. gauges are cheap at autozone or similar places.
