We diagnosed this Chevy trucks power windows, door locks and door speakers in part I and here we are with the fix. Gary: Eric great vedio. I had to replace my front door look on my GMC Serria 2008. I had the &# thing in and out of that door at lease three times. My big flub was dropping a bolt down inside the door. I had to go fine a magnet to fish the &%# thing out. Took two days to finish my lock replacement. Guess what now I got to work on the drivers side rear door lock. It is hit and miss on unlocking but locks okay. I had read somewhere that General Motors had problems across there line with their door locks. Anyway I enjoyed watching you fumble with removal and installation like I did. The only thing better was you keep losing your pocket screw driver. I don't have one. LOL Wounded if it was a Dorman product?

Just watched both vids for this truck hoping to get some insight into a problem I'm having on my '10 1500. Wanna take a stab at it? Driver door lock, will not lock with driver door switch (no response at all from switch with any lock locks, will unlock driver and all doors from driver switch, pass side will lock & unlock all doors, key fob will lock & unlock all doors, all doors lock & unlock when going between park/drive & vice versa. Driver switch replaced with factory GM switch - same result. Have no schematic so not sure where the wires go. To the BCM? Does it control each door individually?

I have to say, if you replaced the speakers in cars with quality replacements and not the factory garbage, you might not have drivers failing in a few months time. For what you fork out for replacement drivers from a dealer you could pick up a good set of aftermarket speakers with adapter brackets and wiring harnesses from a certain online retailer that will remain nameless (lest I be labeled a shill. I understand your gripe with aftermarket gear but if it's done properly it doesn't alter anything and fits just like the stock gear but offers better sound and performance/longevity.

Very helpful videos for diagnosis.
My problem still remains tho (unless 3 master switches and 2 actuators were both pooched from the wrecking yard)
All doors lock with the fob and switch panel minus the passenger front. Changed the actuator, no fix. Changed the master switch, no fix. Checked all fuses that I know of.
Problem 2, drivers side rear window won't go up or down. Checked for power at the window motor and it has constant (dim light) on both sides of the plug and lights up for up and down.
Put power to the motor and it works just fine

That's my biggest complaint of domestic cars, all the bits and pieces dodads and controls that crap out that are so annoying. And all these parts are so expensive to buy and have installed. My wife has a 2009 Corolla that I have not spent a dime on any of that kind of stuff. The only things I had to do it oil changes batteries and tires. What did this poor guy have to pay for all those parts plus labor to get all that stuff fixed?

Did you know you can clean those window switches and go right back to working? I had one the other day that wouldn't roll up the passenger or rear door. Popped it apart and cleaned it up and right back to working in under 15mins or so. The mirror control was partially working as well but one of the contacts was completely missing when I opened it so couldn't save that one. Just a tip for the future.

hrm how to do those door speakers on GM truck in no time. learn how to do it by feel, pop the lower portion of the door panel loose, prop it off the door with a 2x4, use a ratchet and 8MM socket to remove the screw holding it on, slip the speaker out, unhook, reverse to install. less than 5 minutes per door. Had to do several Suburbans once because of it.

about 26 minutes, you thought that little plug was a polygon. I believe it's actually a trapezoid. I believe I learned that from maybe one of about four times I was ever awake and/or paying attention in school and now that little information nugget, some 30-35 years later, has finally paid off. I feel enriched for it.

My 97 silverado is having an issue, driver speakers wont work, when I push the driver window up or pass window up it unlocks the doors and if I hold the up button it blows a fuse, the driver window was working fine then it started doing this, the pass one did it ever sence I got the truck

Why not just install some aftermarket speakers? Like some Kenwood or Pioneer, or Alpine or something? The speakers in my truck failed a year after the warranty was up, so I installed some 50 Pioneer 6. 5 speakers that are still playing perfect 11 years later now.
