There is really not any good way to get to the wiper motor without getting yourself into a very uncomfortable position in the floorboard of your truck. I am restoring my cab now and it is a pain to get up under that dash. I got some old pillows and blankets to make it a little less painful. You have to get under there to get the guages out so you really haven't saved yourself anything. I'm dreading having to run the wiring harness under there as that is my next step.
