I have an 02 Envoy xl. I had my Viper 5701 installed at a Best Buy. The problem I am having is that the heater does not turn on, when car is remote started. Now, my heater does however work. And when the key is put in the ignition and turn to on heater comes on. I have manual controls. I've searched but the very limited info I found doesn't say how to fix it. I guy who installed it, is a friend of mine and he is stumped..
