Hi Jennie and Matt, I must differ with the two previous suggestions sent back to you that I read on the listserver. The wiper motor is a reversing motor; it is identical to the power window motors 1960 thru 1964, in that it is GROUNDED to the car body via its two attaching studs thru the mounting bracket. There are no rubber grommets to isolate it. Indeed, the wiper motor will not function at all if not grounded to the (-) body of the car. If your motor works at all, then it is grounded, and you should look elsewhere to diagnose the lack of park and stop function. Follow the following procedure: 1/ Disconnect the two double leads ( there's a BLUE + BROWN and a YELLOW + RED) . Get a test light and check for following: With wiper switch in the "OFF " position, AND LEADS DISCONNECTED FROM MOTOR, you should have: BLUE = energized (+) ; all three others (Brown, Yellow and Red ) not energized. With wiper switch to "ON" ( low speed) ( and leads still detached) you should have: BROWN and RED energized ; Blue and Yellow not energized. ========================================== Therefore, if you don't get voltage at the blue terminal when you turn the wiper switch to the off position, the wipers will keep running, and won't reverse. If that is the case, you either have a broken switch or a bad BLUE lead from the switch. to the motor. Or maybe the leads are switched around on the wiper switch. See wiring diagram in service manual. ========================================= NEXT DIAGNOSIS : connect both terminals between wiring harness and wiper motor. Using the test light, check for following: BLUE WIRE: will be energized when wiper switch is in the "OFF" position. Will de-energize for about 2 seconds when turning wipers on, and will then re-energize as wipers are running. Will STAY energized when wipers are turned OFF BROWN WIRE: no power when switch is "OFF" . Will be energized when switch is turned on, and while motor is reversing. RED: Energized when wipers are turned on. Voltage varies with speed selected. OFF when reversing or turned off. YELLOW : Energizes when reversing ONLY. No power when running or when parked. ========================================== other problem solving: when turning switch to the "off" position, the motor reverses but does NOT shut off. That is due to a gummed-up plastic cam under the gear cover... remove the 4 or 5 screws that hold cover in place. You'll see a larger white plastic cam that is activated by the motor, and goes round and round...and a smaller plastic cam that contacts the larger one, which is connected to the on/off switch thru the metal plate. spray some WD-40 or similar and flick this smaller cam back and forth until it frees itself. It is spring-loaded and should return freely to its rest position. It is easy to free it up. Once freed up, reassemble cover and now, when the wiper motor reverses, it will engage that cam and turn the motor off after one revolution. =========================================== It is not especially hard to work on this with the glovebox removed.
