Hi, I have Silverado LS 4.3L V6, 150k miles, year 2006 and I have one unaltered problem with heating and blowing systems in my truck. Sometimes it won't turn on at all, sometimes it won't turn up to full power, sometimes it doesn't turn off even after the power is off and the door is opened. I have already changed my 3rd blower motor and new electric system at local truck dealership in ND, but heater system steal not working correctly. I like my truck and have no complaints at least, only the damn heating system. Any other silverado drivers with heater system problems?

When you changed the blower motors, did they change the resistor? You say they changed the electric system. What did that include?

On another forum site, there's a "how to" article on the problems with the heating and AC controls, and how to deal with the problems.
