I have been told my door unlock receiver module on my 2007 four door Z71 is bad. The symptoms are no communication with the TPMS and the keyless entry won't work. Both fobs are fine so it's not them. Can anyone tell me exactly where it is located please? I think I can replace it myself if I can find it. Thanks!

See if you can find the fuse that says DSM (Drivers seat Module, Remote Keyless Entry System). Should be in the fuse box under IP. If not look in your Owners Manual. Remove the fuse for about 20 minutes. Then re-install and see what happens.

That would do the same thing. But it will also reset every module in the truck plus the ECM. I would just pull the fuse. I would just deal with the Keyless Entry for now. Disconnecting the battery usually doesn't cause any problems. BUT there have been times that it does. I have seen it lock up the theft module. And then you would have to deal with that.

Well I did it just like you said but it didnt work. The tech who fixed the air bag issue said his machine was claiming it was the unlock module. Supposed to be on the drivers side somewhere but he was real vague about exactly where.

I pulled two fuses, there were located in the panel on the side of the dash, large black boxes with 5 pins, try that, mine were pulled for 5 hours at least, good luck

What I found in the rear drivers side post was an Omron unit that had BCM on it. Small print said Body control monitor, not module, but I bet it is the module. Took drivers side post apart where the seat belt is and didnt see the RCDLR there either. Anyone got any ideas?

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
