its like 14$ at oreillys for the motor, should take you about 5 minutes to put the new one in. i changed one out in my old 81 awhile back. they always go out when its the most extreme of temperatures it seems like.29 years is a pretty good run time. if you have a haynes manual it should show the steps to replace. if not its on the passengers side of the motor sitting on top of the box connected to the fire wall by like 5 screws? just take the old plastic fan off the old one and put it on the new motor you buy.
