Need help with electrical component of wipers on a 69

Re: Need help with electrical component of wipers on a 69

Thanks Dave. I used a service bulletin (I think) to "bench test" the motor even though I left it in the car and the motor works perfectly which is a relief because at least I know it works. Now the problem seems to be that the RH wiper arm, although it unmistakably moves to the park position, does not recede into the cowl enough to depress the wiper door safety valve so the wiper door can close. It's as if the wiper arm isn't mounted on the shaft at the right angle, although I'm not sure if this can be adjusted.

Anyone ever see this problem?

Mike,
Are you referring to the interlock vacuum switch mounted in the cowl? It's depressed by an intermediate arm connected to the wiper arm shaft, not the wiper arm itself.

I think the position of the interlock switch is adjusted using its slotted mounting holes.

Mike,
What did you do to test your wiper motor? Did you apply 12v to the red wire and make sure the motor was grounded? My service manual does not have a testing procedure.
