Got a issue with my heat in my 2000 Jeep Grand Cherokee Laredo 4.0.


When you turn on the heat it IS HOT coming out of the vents but not near as hard as it should be. A friend of mine had a new blower motor and fan assembly he had bought for his Grand Cherokee so I changed it just in case because it was free but still no change. When you crank it up on high it sounds like the fan is running wide open as it should but not pushing out near the heat as it should be. Didn't notice this until the weather turned cold..


Any Ideas or common problems??
