    The wife had an 03 Gran Prix with the same issue, there was a switch in the center console that went bad. Good catch, I would have jumped right on the incorrect component. Stay safe Brother

  2. Avataaar/Circle Created with python_avatars Dubious says:

    This vehicle needs an electrician, not a mechanic.

  3. Avataaar/Circle Created with python_avatars Daddyoh says:

    Had a similar issue on a 2005 Tahoe after another tech installed a new switch. He didn't rotate the new switch enough to match the old one. I pulled the switch out and rotated it two more clicks and reinstalled it and it worked fine after that.

  4. Avataaar/Circle Created with python_avatars nitrous07me says:

    If you cycle the shifter from park to drive quickly & sometimes hit the shifter with your palm while in park it’ll let the key release, that’s how I usually condemn a shifter

  5. Avataaar/Circle Created with python_avatars jafopt says:

    My first thought is they were tricking the computer to run on lower octane gas with that plugin.

  6. Avataaar/Circle Created with python_avatars derek palmer says:

    What about the feed from the fuse box to the gearbox switch is there any issues with the feed. It might have a break in the wire .

  7. Avataaar/Circle Created with python_avatars Noonehere says:

    Just drill a hole in the bottom cover and show them how to push something small in to push the solenoid free…..and maybe someone will eventually figure it out and steal it from them! Problem eliminated…..

  8. Avataaar/Circle Created with python_avatars d455ave says:

    One of my cars developed a problem,, it would not idle. Let off the gas, and it just shut down. LSS- after some troubleshooting, I discovered that the wire inside the engine harness, that controlled the idle air solenoid had a break. Inside the insulation.

  9. Avataaar/Circle Created with python_avatars bobbg says:

    You take thoses modular fuse boxes out you should spray all the male and female connections with tunnel cleaner, like they used to use on tvs that you manually changed channels with, it will clean and lub all of them up to help stop corrosion
    Even changing one out you still need to do that. As for sevral problems that tells me it could be the main buss that pulls from the battery .
    Also a good way to clean contacts is the eraser on a number 2 pencil youd be surprised how much shit you can get off metal with them.

  10. Avataaar/Circle Created with python_avatars Jay Stevens says:

    We all could use a Hummer

  11. Avataaar/Circle Created with python_avatars general says:

    My mom's Hummer h3 sunroof leaks or might be the drains for it is leaking too where's this place located at the point out how much it cost to redo it

  12. Avataaar/Circle Created with python_avatars Jeff Briscoe says:

    The H2 are garbage going by my aunt. She put them together in a dissembling line all so she couldn’t purchase one either because she knew all the problems that they had. She said Better off getting a military Hummer.

  13. Avataaar/Circle Created with python_avatars Alex Staten says:

    Thank god I’m not the only one that thinks wide ass fender flares on a skinny wheel base looks stupid as hell

  14. Avataaar/Circle Created with python_avatars Sergio Jimenez says:

    GM is notorious for electrical issues🙄

  15. Avataaar/Circle Created with python_avatars bobbg says:

    Test airbag collection sensor crash it into a brick wall. If the airbags don't deploy replace frt clip and broken sensors

  16. Avataaar/Circle Created with python_avatars bobbg says:

    Shifter linkage, probly has a hot wheel shoved under the shifter.

  17. Avataaar/Circle Created with python_avatars bobbg says:

    Stalling cheap Chinese made injectors sold by pep boys or some auto parts store, not a GM factory part. Like thats any better.

  18. Avataaar/Circle Created with python_avatars bobbg says:

    If I can pull a humvee not hummer into a 6×7 garage door that H2 will fit no problem. Yes a real mitilary Humvee owned by the US mitilary, dam thing drove like a tank no creature conforts.
    Tottaly unlike hummer or H2 by the way all 3 fit into a 6×7 foot garage door.

  19. Avataaar/Circle Created with python_avatars HUBBABUBBA DOOPYDOOP says:

    I wasn't aware there is a PCB in that module.
    I thought it was simply a plastic molded box with fuse
    and relay blade terminal "extenders"🤷🏽‍♂

  20. Avataaar/Circle Created with python_avatars Sadayan Ebramsah Ismail Ghani says:

    KTM bikes owns this Hummer?

  21. Avataaar/Circle Created with python_avatars T. J. says:

    Those fuse blocks are a nightmare on GM and Chrysler products, you'd think Ford would do the same but they got cool stuff like frame mounted fuel pump modules that will just corrode a hole in the entire thing. Gotta love electrical shorts.

  22. Avataaar/Circle Created with python_avatars B. Powell says:

    Maybe spray some key lube in the ignition key slot !?

  23. Avataaar/Circle Created with python_avatars Aaron Jubinville says:

    Keep up the great work man you are amazing and I look forward to watching part 2

  24. Avataaar/Circle Created with python_avatars Christopher Wise says:

    these solenoids are freaking stupid. if a battery is dead, it locks the key in the acc position keeping power running and draining the battery even more. i deal with crap on a daily basis at work. i have to hook a jump pack up to get the key out before i can even run my battery and charging system tests…

  25. Avataaar/Circle Created with python_avatars Troll With A Purpose says:

    calling bad key transponder made worse by the ODB plug in battery drain

    so, fuse box with intermittent cuts will also reset that circuit…should put lithium or dielectric on pins and plugs so it don't corrode again

  26. Avataaar/Circle Created with python_avatars Nate Davis says:

    138,000 miles? So that's about 10,615 gallons of gas!

  27. Avataaar/Circle Created with python_avatars Kevin H says:

    the connector on the ODB port is for the stereo. allows the aftermarket head unit to read and display vehicle info through the use of an idatalink unit (maestro rr/etc)

  28. Avataaar/Circle Created with python_avatars DO NOT RESPOND says:

    As these old vehicles age it will cost a fortune to keep um running.

  29. Avataaar/Circle Created with python_avatars docgiggles130 says:

    Nice Suburban you worked on here. Those factory body kits are very well done…

  30. Avataaar/Circle Created with python_avatars jonathan bell says:

    Makes me want a Hummer H2

  31. Avataaar/Circle Created with python_avatars haywoodyoudome says:

    Had a similar issue with the wife's old Subaru Forester. Gear selector switch intermittently stopped working as a result of a sugary beverage being spilled…..

  32. Avataaar/Circle Created with python_avatars Jethro Tull says:

    Resistive connections are a headache and the high impedance / low load of a DVM can actually make the job more difficult. You may see little or no drop from a circuit with corroded connections until the circuit is subjected to a load. I often laugh when I see somebody pronounce their battery is “good” because it has 13.X volts under No load.. LOL. As a matter of fact a simple light probe may do better then a DVM.

  33. Avataaar/Circle Created with python_avatars Neal Fenster says:

    The heat in the engine compartment could affect the fuse connections and cause the other intermittent issues. I am always jealous when i see you use the power ratchets, after remembering all the sore wrists i had using regular ratchets! I really enjoy your videos.

  34. Avataaar/Circle Created with python_avatars Kevin Felty says:

    Cool

  35. Avataaar/Circle Created with python_avatars Kevin Felty says:

    Some times that's all it takes.

  36. Avataaar/Circle Created with python_avatars SPC Calhoun 4653 Life Safety says:

    Hey whacha call a hummer h2 that was flooded

    A hummer H20

    he he he…

  37. Avataaar/Circle Created with python_avatars Patrick Brady says:

    Thats a diagnostic… Wish more mech were like you

  38. Avataaar/Circle Created with python_avatars Clark Kent says:

    Here's how you fix those you pull the pin on it you throw it inside there and you get back problem fixed

  39. Avataaar/Circle Created with python_avatars Vern Freeman HTD4LIFE says:

    no way I think it's a little thing you took out of the module connector under the dash is the problem it's all part of that plug it back in and check

  40. Avataaar/Circle Created with python_avatars James Sampson says:

    What was the plug that you pulled from the OBD II plug used for. Thanks, great video as always.

  41. Avataaar/Circle Created with python_avatars Joey Layman says:

    What about that wire you pulled of the diagnostic plug

  42. Avataaar/Circle Created with python_avatars Sqwince23 says:

    Your wiring diagram says the supply of that circuit is "PCB Relay Energized" check the relay they tend to stick.

  43. Avataaar/Circle Created with python_avatars Stephen Caine says:

    It’s a Chrysler vehicle. That’s the problem.

  44. Avataaar/Circle Created with python_avatars bobbg says:

    Diagnosed, it uses more gas then anything on the road today. Must be owned by a gas station owner.

  45. Avataaar/Circle Created with python_avatars Don's Junkmail says:

    Bad sound activated hum switch.

  46. Avataaar/Circle Created with python_avatars August Inter-nation (Augy) says:

    WOW! Ray, you managed to take diagnosis to a new level!…Excellent video and well done!
