My heater motor seems to have lost some power, its about a year old and just doesn't seem to have the output my friends jeep has by a long shot. It seemed ok until I started messing with a few other jeeps around my year [88] and they move a lot more air. I know the renix wiring sux way bad and don't want to mess with it to much, so is there a way to run an alternate power to it so I know its getting the full 12-14 volts and see how it worksor makes a difference??
