    i had an intermittent wiper motor in the shop. I looked at the wiring diagram and it showed the relay to be in the box. This is a 2007 Chevy Impala 3.9. The diagram showed two main feeds to the motor (low and high). How can I test the relay when its made into the fuseblock, underhood.

    Guys thanks for this very information class on electrical troubleshooting on automotive systems……yes cars are being are being built with more and more electronics so us techs have to sharpen our electrical troubleshooting skills….by the way I do work in the military aviation field as a civilian contractor and we have lots of electronic devices on the board so we must use schematics when we track down component that is not working to repair…..specially from anolog to digital powered components…..again thanks for your classes!
