There is a number on both transistors. Take a more in focus picture of the one in the right of the last picture. If you have a tube of heat sink compound, put a drop on your finger and rub it on the transistor on the left side of the picture. Rub most of it off and you will be able to see the number on it.

I did that and google came up with nothing... I even brought the part to a electronics store and he said that he is sure he has the part but the numbers dont come up with anything.. he also said that it could maybe a in house part that Chevy made or something 🤷‍♂️..
