I had a BCM replacement due to truck's ABS and theftlock light staying on which prevented truck from starting. After new BCM I drove for like 30 minutes and the theftlock, ABS and TPMS light came on. The gauges in the cluster started moving up and down but the truck was running fine. When I got home the radio went off while truck is running. After turning off truck won't start unless I wait for like 10 minutes and all the lights are gone. They come back on after driving for a while.
Do you
have the same problem?

It sounds like the BCM went out again or there is a bad connection somewhere. To be sure lets do a CAN scan which is the future of automotive repair you can get a CAN scanner from Amazon for about $50.00. here is a video to show you how:

Problem with the lights inside the car. There is nothing on the counter except the check engine. The gauges are not working. The radio is not working. Blower the same. The switch to change the drive to 4x4 also does not work, the same for electric windows. The car starts and runs normally, but after turning it off and even removing the key, the car continues to run. After disconnecting the clamp from the battery, the car goes out. Fuses checked and okay, none blown.

These are all controlled by the BCM. we should check all fuses first with the key on this guide can help with the fuse locations below:

Unless you have a pass through programming kit for a good scan tool and download link for the correct flash for that BCM, you need to get a rebuilt unit.
