how to change wiper motor? 71 Suburban

[rsavage]

You have to take the wiper arms off and remove the cowl to disconnect the motor arm from the wiper transmission arms. You then remove the wiper motor from under the dash. Not bad with a non AC truck, but more challenging with an AC dash. Remember how the linkage is positioned and connected. Do not put the wipers back on the truck until you are sure that the wiper motor is in the park position. When you remove your wiper arms notice that there is a little clip that has to be held back so that the arms will pry up off the serrated trunion.
