May be the heater controls assembly in the vehicle....this thing you may have to get at a bone yard....dealer only part...wouldn't want to pay dealer price...the fact that you have no high speed AND you are having a problem with the blend/regulator door for defrost/heat,etc..leads me to believe it is the control assembly

I would suspect a short in the blower motor. Lower speeds are through resistors, high speed is direct to the motor. Unplug the motor and try going through the speeds.

2000 jeep grand cherokee, only blow out a little air even when the blower on hi,,you have to put your hand next to the vent to feel the air


you may have had something fall down into the defrost vent and it has worked its way down and is blocking the air flow thats trying to come out the vents,near the blower motor.also does it sound like the blower motor is spinning on high speed or at a lower speed,you could have a slow turning blower motor.
