About your vehicle.

That could very well be the wiper switch but there is no way for me (or anyone) to know without some testing.

.

Being that we are not sure as to what the customers want to accomplish by asking a question, do you plan to check it or repair it yourself?

yes we are going to repair it, just wondering if there was a relay somewhere or something like that. on some vehicles there is a low and then a high speed relay
Expert:  Super Mechanic replied 4 years ago.
That is actually built into the wiper module, (on the wiper motor) but let me post these tests for that concern.

The numbers below refer to the step numbers on the diagnostic table.
  1. This step tests for continuity through the 390 ohm resistor in the windshield wiper/washer switch.
  2. This step tests for continuity through the delay resistors in the windshield wiper/washer switch. The measured resistance will change in sequence from low to high as the delay speed is increased.
