How should I
The previous owner disconnected the windshield wiper motor and I need to fix the issue so that I can pass the Texas safety inspection. I removed the switch assembly (inside above gauge cluster) and everything was connected and worked appropriately.
Inside the engine compartment everything is present and working as it should except for the wiper assembly motor, it refuses to move the wiper blades. The vacuum lines are connected and have good pressure to lift and close the wiper door cover.
Is there anything that the previous owner could have disconnected under the passenger dash or in the engine compartment?

The plunger is depressing the switch on the firewall and the interior overide pull switches are in the upward position. I'm going to pull the console and check the relay switch there. Its an electrical issue for sure.

You can perform a bench test while the motor is still in the vehicle. it will help to know if it works. go to the Willcox troubleshooting page. you need a multimeter and you need to check power at your leads, ground at all the switches and relays, and count nuity through the switches. if you trip the switches and the door opens, I would say the wiper switch is working, the relays are mostly working, but it doesnt tell you about the over ride switch or the door open interlock switch. I would check those with the meter

Hi St,
You mention checking the vacuum override switches but what about the wiper arm control switch between them?
The switch should be turned clockwise (to the right) in order for the wiper motor to operate.

Alan

I have them as you described, I'm going to continue troubleshooting. The relay switch on the passenger side of the wiper compartment might need to be replaced.

Hi St,
The 3 port vacuum interlock switch in the right side of the wiper door is only a vacuum switch….it is part of the control of the wiper door movement, but not the wiper motor electrical circuit.

Other members need to check on the restrictions in their state. In Mass there's severe restrictions...., to and from shows only, low miles, lots of limits. Just saying so you dont just jump in. I pay $100 for veterans plates every 2 years, I think it would be $60 otherwise, no restrictions, $35 for a state inspection. It would be less but I put 3000 miles on my vette this summer so I avoided those plates...
