no communication,gauges,windows,locks,dome lights,4w,I already checked alot of grounds including the one behind the block dont know where to go from here only things that work are the speedo and RPM |
 |
The things that come to mind are the ground at the top rear of the engine which you said you checked. The grounds at the left frame rail under the truck, below the area where your left foot would be. Also check the fuses. Don’t overlook the pal fuses in the underhood fuse box. You mentioned “no communication” can I assume you have a scan tool to work with? |

yes i have a handheld |
|
|
i also checked the plug on the module under the driver seat |
|
|
also from the beginning this all was working fine then while passing a power wire for the radio i removed the cluster and the car was off i noticed the dome light go out but when i plugged in the cluster it went back on …later i unplugged the cluster again,but i did not realize the car was on ….i saw the dome lights go out but when i plugged the cluster back in the the dome light never came back on maybe something happened because the car was on .. just a idea.. |

since then i tried a new cluster ,pcm and bcm and nothing worked |

Except for setting codes that you would not be aware of you won’t cause any issues by disconnecting the instrument cluster with the ignition on. I have done it at least a thousand times. Have you checked all fuses yet? They need to be checked to make sure none are blown and all are properly powered that should be. Do you have a multimeter to test with? |
