If you mean by "increase it" when we turn up the force of air (fan/blower), no. When we start the truck, the fan knob is in the highest position. Ittakes about 15 minutes for the fan and cool air to come on. But then in a few seconds, the fan blows only VERY low, almost nothing. The air is still cool. Turning the fan knob down low and then right back up again doesn't do any good. Someone said they think it might be a grounding problem.
