silverado_ss_04 Posted May 12, 2011 Author Report Share Posted May 12, 2011 sounds like a bad ground imo. there is a few , try checking out the one under the driver seat on the frame . that is a common spot to get a bad ground and it goes to the bcm. cleaned both of them with no luck Quote Link to comment Share on other sites More sharing options...
silverado_ss_04 Posted May 23, 2011 Author Report Share Posted May 23, 2011 (edited) the guy who is trying to figure out whats going on says he has checked everything over in the truck for power and everything seems to be powering up fine. he also checked over all the data lines and they are also working, also tried another pcm and bcm with no luck. im not sure whats to check next, sounds like my truck is almost ready to get hauled away for scrap Edited May 23, 2011 by silverado_ss_04 (see edit history) Quote Link to comment Share on other sites More sharing options...

paulguy Posted May 23, 2011 Report Share Posted May 23, 2011 Driver door module. You said windows and locks aren`t working. The pdm also controls the keyless. Quote Link to comment Share on other sites More sharing options...

The pdm also controls the keyless. we took the driver door panel off and he checked everything over and he said its fine. where is the ddm module? i can try replacing it with one in my dads 05 silverado?

paulguy Posted May 23, 2011 Report Share Posted May 23, 2011 (edited) It`s the the switch panel on the door panel where all the plugs plug in. Like the bcm, it has to be programmed by the dealer, so I`m not 100% sure if it will communicate with the bcm if it`s not programmed, but it can`t hurt to plug it in and try it. I think programming is just for certain options. Edited May 23, 2011 by paulguy (see edit history) Quote Link to comment Share on other sites More sharing options...

paulguy Posted May 23, 2011 Report Share Posted May 23, 2011 Take a look at this diagram. g203 is behind cluster below drivers a-pillar. Its ground for the radio, ddm, cluster, common with stuff that`s not working. http://content.chiltonsonline.com/content/images/WD/GM/014/WD_GM_014557.pdf Quote Link to comment Share on other sites More sharing options...
sprayed99 Posted May 23, 2011 Report Share Posted May 23, 2011 I'm guessing the guy that is helping you has a Tech II for programming all of the modules you have tried? Quote Link to comment Share on other sites More sharing options...
sprayed99 Posted May 23, 2011 Report Share Posted May 23, 2011 you need to go over every single ground in the truck to verify that they are all good. You can do this with a multimeter.....and simply use the contunity test feature and check all grounds from the grounded point to the negative terminal of the battery.
