Basics: 89 Laredo, 4.0, Aw4, 242.
I replaced the blower motor as it's bearings were singing, and ever since I have no noticable airflow in the ductwork. However, when the jeep is warming up with the heat on, the cab is comfortable after 10 minutes, I just don't have any air flow... I checked for:
vacuum leaks - none
blower motor working - it spins at all four speed settings
Fan blade - still attached to motor and it is spinning
vacuum actuator under blower motor in cab - it doesn't move (what does it do?)
Temp control switch - it moves some baffle (I hear it move)
Fuse - still good (replaced it once which lead me to realize the old motor was drawing too much current)
But when I place my hands over any vents, zero air velocity...
Any ideas???
