The vacuum control valve is starting to leak. Somebody else can maybe come up with a solution.My 65 also has a wiper lever that creeps from off to on, then the wiper starts wiping with no warning. Just realized the wipers are hydraulic so can you tell me what is going on?
There most definitely is a control valve on the switch. How else would you turn them on or off. My '57 works exactly the same way.Ward,
The 65 Thunderbird had hydraulic wipers and ran off the power steering pump, so it doesn't have a vacuum control valve.

I stand corrected. Never got into those systems when I had my '66. Hydraulic? Never heard of it. Didn't know they tried that before going to electrical. I can hardly imagine the plumbing issues.Ward,
Your 57 wipers are vacuum controlled, that's why the control valve is on the switch. The control valve on a hydraulic wiper system is on the motor. I read the instructions in the Shop Manual and it states to adjust the control cable so that the control knob on the instrument panel moves the valve control lever on the motor from off to full on.

The switch and the cable are one unit, the adjustment is made at the wiper motor end.does it say where the adjuster is, which end of the cable?
