I have to wonder what some of those other shops would have done with this issue. Those who convince customers to pay for parts replacements. And a week or so later, the car comes back with the same problems, they do the same thing again by chucking parts are it. As I know it, a shop shouldn't get paid for things they do that doesn't correct the problem, only the thing that does yet shops collect undue fee's from their customers. Interesting how that occurs to way too many customers while Eric does his diagnosis for a one hour shop charge (in most cases) then explains to the customer what he has found and which path to take in correcting the problem. I wish there were more shops and dealerships who would perform their diag the same when they really can't make the call with 100% certainty. Too bad some of these connections and termination issues can't be taken to the manufactures and say, hey, these parts are failing by defect in design, buy the car back until you learn a few lessons about design/dependability engineering in electronics.

Did this solve the issue for the vehicle owners? I am currently dealing with the exact same issue with my Chevy Cobalt. Same kind of car manual windows and locks. All the gauges will start wigging out and the transmission will shift really hard. I've taken it back and forth to my local Chevy dealer for the past 3 years for the same issue. This week alone I have paid out 460 to replace parts and then they came back and said that it is a computer issue that is going to cost me another 890. It will be at least 10 times or more that I have taken the vehicle in to have the same exact issue fixed. My local Chevy dealer ordered the computer and are planning on installing it Monday. Do you have any advice to offer me?

I fixed an issue on a Fiat vehicle with a connector for the electric windows that would randomly start and stop working. Normally after vibration. I traced it to the pins in the connector. They seemed ok. Cleaning and messing with them never fixed it. My friend who owned the vehicle told me to chop the connectors and solder the wires together. The van is only 2 or 3 years from the scrap yard anyway. Works fine since. Connector problems are a pain.
Top video Eric. Great to see some CAN stuff. My CAN and general networking knowledge on cars is terrible.

Looks like you have the OTC diag equipment out. Thats my favorite B. O. B. But really dont like there scan tools at all. Very disappointed in them. But as you say thats just my personal opinion. Love your diag videos buy the way. The big three. South main. Pine hollow and last but definitely not least New level auto.

My 06 Nissan Frontier did the same thing, the U code was the 4WD module under the dash. Cleaned the connections, problem solved. Network's happy, no problem with the 4WD module before and after cleaning and the code hasn't come back. Love those intermittents! They are the curse of the automotive industry!

I have a 2007 Cobalt, very similar to this one you show. I get the same symptoms in the rain. When it's dry all is good. In the rain I get the codes. I've had it happen a few times. Usually it happens just when i start the car. Recently it's happened while driving. The car goes into low power mode.

At the dealership we the database tool. We can see what module are on line and which are not. The first thing I do I check resistance at the dlc connector then go from there. Split the system in half check for 120 ohms, then move Towards the side that doesn't have 120 ohms. You know the rest.

Another thing. When you break out the schematics and go through them step by step during your troubleshooting routine is priceless. I have learned a ton watching your troubleshooting methods. A million thanks to you. And again, Kay Man scared the hell out of me, LOL!
