If I use an online manual is it easy enough to change out the heater motor and resistor myself?
heater motor and resistor on 1999 Plymouth Breeze
the blower motor in most cases are located on the fire wall on the passangers side of the car. there may be 6-10 mounting screws. Disconnect the negetive cable to your battery first. Then un plug the power wire and hose. Then undo the screws. Put the new one in place. Make sure it does in exactley the way the old one was mounted. reverse steps
it should only take a couple of hours to change both
yes u can do it.
