Astro Pneumatic Tool Company sent the keys to the mystery box. It's time to look inside 😁

People argue all day about buying "American-made" vehicles. Meanwhile I'm over here installing genuine GM parts that come with a "Made in Mexico" card large enough to be seen from space 😅

Boy, I really thought I was getting myself into one of those "ever since" situations.
In the end, it worked out well because I called the customer, and they confirmed they had been experiencing this problem. Why wasn't it in the pre-scan history from the day before? Why didn't it act up when I pulled it in yesterday? Who knows.
Maybe it's partly on me for not taking it on a longer road test, but yesterday's diagnosis didn't even require a test drive.
Live and learn, document everything, and be thankful when you have an honest customer!

Another victim of aftermarket garbage. Car came in with a complaint of parasitic draw, intermittent no start, and key fobs did not function. I love doing parasitic draws on a Subaru because these older ones time out in about 30 seconds after you shut the key off. This one was hanging steady about 90 milliamps. Anytime in the past I've seen 70 to 90 milliamp draws 99% of the time something is plugged into the data link connector or there's an aftermarket alarm or remote start. Took a peek under the dash, saw the typical rat nest of wiring, took it all out threw it in the trash and I'll be darned all the problems are fixed. Parasitic draw now is 12 milliamps, key fobs work, car starts just fine. I've probably removed over a hundred of these in my career 👍🏼

Just a little reminiscing how a shop used to be able to carry about three oils and cover most any Asian or domestic vehicle. Nowadays I think you can carry about a dozen and still not have enough 🤷🏼‍♂️
