In Seattle with my 2000 Jeep TJ that I like to run through mud. Been throwing parts at several, separate and accumulating problems to no avail. Then girlfriends vehicle had functional low beams but no high beams so she took it to a shop where they replaced both headlamps with predicable results. I have reached critical mass. I have the time to learn this. Started looking online, found Matts Youtube site, then this site.
This site is SO helpful and instructive. See it on the whiteboard, Hear it audibly, See it in a simple garage-floor layout, see it on the car, see it on a meter, see on it a scantool. I’m getting it now, after all these years.
Thanks,
FM
