Can anyone tell me if the wiper motor from a "77" 123 will fit/work in the 79 300 SD?
When I turn on the wipers on the SD the arms move an inch or two than stop. If I reach out and pull up on the arms they began to work fine. If I just wait to see what happens they will start working on there own after a minute or so. Should I assume the motor needs brushs? By the way, is the motor under the dash or? Thanks in advance.
