1990 - M. G. M.
All suggestions are greatly appreciated.
My blower motor does not put out the air that it should and since I have already replaced it twice I am looking for answers or suggestions. Vacume system has been checked and no leaks found all actuators move as they should, Resistor has been replaced. I can hear the blower motor change speeds when I move the selector from low to high. Barley any air coming out the vents and defrost, more air coming out the floor than the vents or defrost. Still not near as much as their should be. When selector is on high air coming out is like on low at floor and less above.
I just checked the voltage to the blower motor and recorded the following readings. This was checked with the engine running ( incase that makes a difference)
Low - 6.7 v
2 - 8.5 v
3 - 12 v
High 14 v
Thanks for your suggestions
