Hey, I just hooked up a remote start kit a couple of weeks ago. When I hooked it all up, my heater/air conditioner worked fine. NOW, when I start my truck with the remote, my heater blows cold air and the air conditioner blows hot air. This problem comes and goes. Sometimes it works right, sometimes it doesn't. ALSO, my radio shuts off and on all the time. It stays off most of the time. When it does work, it usually only works for about 5-10 minutes and then just shuts down. Any ideas? I was thinking maybe it had something to do with the accessory wire. But I unhooked it and I'm still having the same problem. I don't think that it was just a coincedence that my radio is malfunctioning and i need to repair the a/c system. I'm stumped here, someone help.
