Testing Wiper Switch Continuity

charliec said

I should see between 0.0 and 0.5 ohms at each one if the switch is good

The problem with ohm meters is that they don't tell the whole story.

When there is a load ( motor, light, etc.)
The contact can be bad.

Without a load it might read good.

To do a more indepth test you would need to place a load across the contacts and measure voltage drop.

IMHO

If the contacts ohm out ok you are probably good to go.


If you have been having issues with the switch then a load test would be in order.
