Interesting results, wipers won't park- New Update

The wipers on the white 88 have rapidly gone from parking most of the time, to parking occassionally, to not parking at all. Figured it was time to dig out that musty old article on fixing the plate guides on the motor/switch assy and put it to use. So I disconnected the harness at the motor/switch, took it out (love undoing the clip on the arm). Low and behold there was nothing wrong with the guides or the plate inbetween??? Lubed it up and reinstalled and decided I was going to have to (sob) diagnosis it electrically. Got the books out for the electics and started to take the cover off the steering colume to get at the switch.

Then I thought, just for S & G, lets try it one more time. Low and behold the wipers parked perfectly. Tried it a few more times from all positions and they parked every time.

Conclusion, if your wipers aren't parking, try unplugging the connector at the wiper motor a few times, and see if cleaning the terminals solves the problem

In the course of reclaiming my 88TC, I have pulled apart many connectors, and occasionally found a problem with one of them. When putting them back together, I always apply some silicon dielectric compound to one side. IMHO this helps to prevent dirt, water, & corrosion from giving me problems in the future.

Pete, if the wipers do not have a good ground at the motor once they are started they will never park.

DonH. Are you saying it might have been corrosion between the bolts that hold the motor/switch assy to the fire wall and the metal of the fire wall?

Yes Pete. The wiper motor switch has to be grounded in order to turn and reverse the current so the blades will park. The wiper switch, when turned on supplies both the power and ground for the motor. When turned off the ground path is cut in the switch but current continues to go to the motor to get the motor to the position where the motor switch will move into the parking position where the current flow will be reversed and the blades will pull down. The reverse current ground is through the motor case. This surprised me when I was replacing a motor and tested it before installing and found that it would not shut off until I grounded it to the car body.

Tokk the car out in the rain today. Turned off the wipers and they would not park. Tried it seferal times from different switch settings and could not get them to park. Back to the drawing board.

See the pics.It's on the driver's side of the fire wall, near the hood hinges. Take the whole thing out as a unit, don't just take the motor off

The other pics show the guides and the slide plate. The guides bend away from the plate and aloow it to flop around. If they are not as shown in th epics, they have to be bent back to the positions shown. Mine were OK, as you see them in the pic.
