Hi everyone, I'm new to the forum but have been looking around for a while - good discussions. I have a heater problem with my 07 base model GP. The heater works normal on defrost mode with plenty of heat, but when I set it to defrost + floor setting the heater cools down to a lukewarm temperature (not comfortable in below freezing temps) and there is no heat or air on the drivers floor duct, even with fan speed on full. All of the fan speeds work properly but no matter what mode I turn the dial , I won't get any air from the drivers floor duct. This system is the single climate control only. I have read some discussions about blend door actuators but not sure if this is the problem or not, and how many actuators does this particular system have anyway? Thanks.
