I am having a problem with the wiper blades only working only on the high speed along with the wiper fluid release tab. The intermittent function and the one time wipe does not work. Would this be a ground wire problem or a switch problem. I got a used assembly switch unit from the wreckers but have not installed it yet as I am hoping it is a simple ground wire issue. How do it test it before I start pulling everthing apart.

Thanks Herman.

Hi:

If it's a ground problem, using a test light, check for power at the motor when the switch is in a position inwhich it doesn't work. Your light will provide the ground and it will light if the power is present.
