So i'm at work today, and the service manager sets me up to work on an '03 Trailblazer. The customer comment column simply reads - will not run, have no idea why, rattle in drivers door. A quick battery check reveals 12.6 Volts. On a hunch... or rather just because it was my first job of the morning and I wasn't quite fully awake I decided to grab a scantool, rig it up and check for any diagnostic codes..... and after what seems like forever, still no response from the vehicles computer. Confused I quickly grab a senior tech from the bay beside me, he sets up his scan tool gets a message ECU unresponsive and quickly deduces the ECU is no good.
I phone the customer for some additional info, turns out his * no idea why * was actually, "well I tried boosting my sons car a few times because it was dead, and after that it wouldn't start"
. He is not impressed to learn that his ECU needs to be replaced and GMC is not flipping the 1600 dollar bill because warranty doesn't cover extreme stupidity. The circuit protection in this unit means that the customer would've had to have left the jumper cables on the wrong posts for quite some time.. or have taken them off and put them back on a few times before the ECU would actually cook the way it did.
He's back at the shop a half an hour later, completely irate, demanding to talk to the service manager as well as myself
. I had a 15 minute sit through of BS listening to this guy piss and moan while i'm trying to make money on a flat rate job, and when I asked him who taught him to boost cars he replies with, "Noone did! Everyone knows red goes to black, black to red, negative to pos.. and so forth"
I can't help but grin which boils him up even more.
"WELL DID YOU ATLEAST FIND OUT WHAT THE ^@#$@^@#$% PROBLEM WITH THE DOOR IS"
".... yes sir, you left some dentistry tools in the door pocket, which caused the rattling sound you heard"
*** Have you ever wondered why your local friendly automotive service technician isn't always quite so 'friendly'? Sadly its because things like this really aren't as rare as you might think.***
Please leave me a few humorous tales of your own.
