Re: 1965 Wiper Washer Woes

Louis,
I can provide a couple of references for dealing with '65 wiper woes.

First, the 1963-1965 Operations Manual & Performance Verification Test Guide does a good job of documenting how the system should work when knobs and button are pressed.

Second, the 1963 Shop Manual deals with repair and trouble shooting. Section 12, pages 18-24.

Good luck.

Regards,
Gene

Louis:

The two wire connector is for the pump soleniod. The three wire connector is for the wiper motor. It sounds like your pump solenoid is working, but you won't get any pump action unless the wipers are on, which will engage the pump pawl inside the wiper transmission. The wipers are 2 speed, and the wiper housing must be grounded. In the following, I am referring to the terminals on the wiper/washer housing.Test as follows:

0. Either remove your wiper blades or keep the windshield wet.
1. Disconnect both connectors from the housing.
2. Apply 12V to the brown wire for the wiper, and the brown for the washer.
3. Ground either the B/Y or the B/LBL wires for the wiper. That should be "Lo" speed.
4. Ground BOTH the B/Y AND B/LBL wiper wires. That should be "Hi" speed.
5. While the motor is turning, either hi or lo, MOMENTARILY ground the DBL wire for the washer pump. The pump should start, remain engaged for about 6 cycles, then disengage.

All terminals at the switch are either "on" or "off", so resistance is either infinite, or zero. It is a three position switch, thus 2 detents. Off, lo, hi. When the washer button is pressed while the switch is in the off position, it will simultaneously rotate to the lo position.

If the washer pump clicks and wipers go on

when you push on the wiper switch, then you don't have an electrical problem.
The washer pump operates off the wiper motor. When you push the wiper switch, it energizes a solenoid on the washer pump, which puts the pump in gear so that a flat rod with a rubber bellows on the end goes back and forth, against the plastic check valve assembly at the end of the pump. It goes through a cycle of about 6 clicks or pumps. Then the pump disengages although you can still hear a very low click.

I think you problem is more with the plastic check valve assembly or the bellows.

See my posts of October, 09 and 03, 2004, for pictures of the check valve and bellows, and a discussion of problems. There's also lots of threads on the Washer pump, this year and just recently, and in prior years in the archives.
Mine is a 67 washer pump which I believe is the same as a 65

Re: 1965 Wiper Washer Woes

I just wanted to thank you all for your help. After troubleshooting, we determined that the wiper motor was at fault. We removed it, partially disassembled, cleaned, and lubricated it, and got it working. We then noted that the washer pump wasn't working, but a partial disassembly, cleaning, and lubrication was all it needed, as well. We reinstalled the unit and everything now works as it should. Can't thank you all enough.
