I believe the headlight; dash wire harness has a ground issue. Where are the grounds located for that? TIPM was replaced and 2 grounds were repaired and now running into this.

The ground for the headlight system is on the right shock tower. The instrument cluster ground g200 is on the left side of the dash, can I ask if the TIPM is new? If not, this might be the problem again. Do you have any codes? I would run a CAN scan which can tell you what the problem is. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

TIPM was rebuilt and installed by a shop.

Okay, the TIPM can be bad again, did you get a chance to check the system grounds, also what kind of problem are you having? We might want to try doing a CAN scan. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.
