The A/C fan blower motor has died on my '85 Ram.


Is there a blower motor and/or squirrel cage available that will push more air (higher volume of air) thru the factory A/C system?

 

The biggest problem most often is the power\resistance problems between the fuse block, the blower resister, and the blower motor.

If you were to wire in a relay for the blower "high-speed" you would have much more hi-speed blower.

have you verified the motor is dead? could also have a bad fusible link. a/c heat stuff is powered by 1 fusible link. if you have power locks they would also share the same fusible link but otherwise they are all alone. otherwise no better motors or squirrel cages

 

As it turns out I had 2 issues:


The old fan motor was so worn out it wasn't spinning nearly as fast as the replacement motor.


2. The foam gasket/seal between the blower box and the firewall was slowly drying up & crumbling after 29 years; has a couple of gaps I could shove my pinky finger thru.


After installing a replacement motor and using most of a tube of clear silicone calking, going around the blower plenum box from the firewall and schmearing up the old foam gasket, then allowing a couple of day's drying time, the volume of air coming out of the dashboard vents is MUCH better.


I still may try sls' high speed relay upgrade.
