Buick LeSabre: No Reverse, Interior Lights, No Defogger, No Power locks

In this video we have a look at a 2005 Buick LeSabre that has a customer complaint of, no reverse lights, no interior lights, no power outlet, no rear defogger, no power locks etc. Are they all related? Let's find out. -Enjoy!

Shops that tell customers to "go pound sand" are forgetting about the internet business review sights. Customers can go online and report their negative experience to the whole world. It can put those shops put of business. They also forget that the customer could be a lawyer, related to a lawyer, or work for a lawyer.

[@jonsey1886]

Or just be good friends with two lawyers....

[@MDAdams72668]

from what I saw the failure was almost certainly NOT related to the work the first shop performed(in fact the customer was aware some of the things were not working BEFORE the elbows were replaced) Tho bad business if they did say "pound sand" I have had customers tell me things about nearby shops I know they would never say or do IMO the module was already bad and the customer noticed the other failures due to "heightened awareness" post repair)

[@jsciarri]

This channel is light years better than EricTheCarGuy's channel in so many ways. Keep up the good work and fantastic content.

[@CubasAutomotive]

They are apples and oranges... ETCG does what he's familiar with, though he's not into scopes and he did lots of work for dealer. Eric O grew up tinkering with things, a family that did this for a living, as far as I know never went to a formal school for wrenching, and exposed to more variety than ETCG, like farm tractors, diesel rigs, etc.

[@montestu5502]

Light years ahead of any car repair channel.

[@jws3925]

TOTALLY agree. I've seen ETCG do some things Eric O. would never do. I don't even watch any of his stuff anymore. The Fairmont project did it for me but I was on the edge anyway.

[@CubasAutomotive]

@@jws3925 yeah, the Fairmount did it for me too, though I do check out some of the topics from time to time, just not so much the repair stuff. Plus the latest was the Mini, and I certainly have no interest there. I just think that everyone has their interests and their own niche, not to say one is better than another.

[@CleanSC]

Two different channels, for sure. SMA is more diagnostic stuff, ETCG was more nuts and bolts and DIY stuff. They came from different beginnings which colors their directions. The Fairmont was not his audience but it was a passion project for him so I wouldn't fault him for it. The MINI Series was very educational on several levels so it was a worth watch for most, whether you fix cars or not. Cliff Notes: MINIs are expensive junk, stay away. A very valuable lesson to be had there, even for techs. Now I know if someone comes at me with one, or asks me about buying one, I know exactly how to advise them. Both good channels.

[@rattmann36863]

Sad that a shop would treat a customer that way. I guess they don't need the business and money to stay open. Keep up the good work. Fixing other folks screw ups.

Thanks, had all those issues, replaced the module and now everything is working again. The Back seat is THE BIGGEST PAIN TO REMOVE. Push and push those clips down and pull seat straight out. Would have been easy to remove from truck but no GM had to put 2 plastic clips in back of seat. Total BS. Glad it worked so cheers to you!!!

Other shop had no class, it doesn't matter if they had anything to do with the failure or not. Never tell a customer to pound sand! However I heard the old phrase "ever sense you worked on my car" more times than I can count. Some how some customers think just because you work on their car everything that goes wrong from there on is your fault. In 45 years I never told one to go pound sand. I did throw one or two out of my shop after they threatened to beat me up!

[@SouthMainAuto]

Thing is this guy is pretty calm. He totally understands, he was just wondering what was wrong and if it had anything to do with it.

For us DIY'ers: The Class 2 Serial Data network on a GM uses a zero to Seven Volt signal; the voltage rests at Zero volts when there is NO communication; the transmitted data is a variable pulse width signal; Class 2 is found at Pin # 2 of the DLC, and is a single-wire network system; and GM uses what is referred to as a “splice-pack” to connect modules and the DLC to each other for network communication. Great video Eric, that little U scope is getting around!

Eric! Bought the uScope using your link! Thanks for linking the basic one. I thought there was only the, "Master" kit. I got the mini bnc to bnc adapter so I can use my Pico leads. In regards to the module, occasionally I see things just randomly die from having the battery disconnected and reconnect. Either that or the shop shorted the alternator, and then disconnected the battery once they realized that's what they should of done (shrugs). Thanks again for all your videos. They've changed my life, and 4 years later I've quit my job and work on cars full time successfully.

Why would any shop tell someone to pound sand? Look the damn car over and see what it is and if it’s possible you caused it. We would never tell someone that. May as well just tell them to never come back again because they definitely won’t.

[@MDAdams72668]

Many shops get a bad rap despite there innocence As they knew they were not involved in anything that should have caused this failure I can understand the unwillingness to "fix it for free" I doubt they told the consumer to"pound sand" more like "sorry sir our work was in the engine compartment and unrelated to the problems caused by a trunk-mounted module" The consumer then bad mouthed the shop and may well have told SMA"they told me to pound sand"

[@leroyjr.4464]

One more test you could preform would be to have Ms O hit a button and watch the data jump on the scope then you would see that data on the network. Also you could test the outputs of the RIM while a button is being held. Alas this probably would have been overkill in the testing department. Fine job.
