I have a 69 Skylark Custom with hide-a-way wipers. The original wiper motor worked fine , then wouldn't shut off. I purchased a new one and it worked perfect & parked correctly, now the car is on the road and the wiper will not work, I went to take the motor out and it started working, then yesterday it will not work. I checked the ground wire & even added another ground wire to the firewall. When the car is switched on the two yellow wires have fire but the other two don't when the switch is moved to the different speeds. Could this be a faulty switch? can I check the switch to see if its working? Thanks Jaye
There is a great video on Youtube where a guys steps thru how to test a motor and switch. If I find the link, will post.
