Okay. I am pretty sure we have an electrical issue, and a ground issue would make sense but may not be what we have now.
However, anytime we get into this territory, we need to start at the beginning and that is making sure that you have a good battery because a weak battery will cause all sorts of issues. Just drive by a parts store and have them load check the battery just to make sure it passes.
If it does and the ground for the module checked out, then I suspect the module is the issue.
However, before we condemn the module, let's just run through getting voltages for each of these pins.
Take a look at the diagram below. If you can get voltage on each of these pins that will help us make sure we are on the same page.
Again, 14 needs to switch your other meter lead to battery positive so that it checks the ground just to double check that one. All the others you will have your other meter lead on a ground.
I suspect most of those voltages are correct because these should be door switches and if the door is open or closed then that will change the voltage. So, if you want to test that as well you can by opening or closing the door based on what pin you are on.
The OL concerns me because that is normally a resistance reading and not a voltage reading but that could be based on the meter you are using.
Feel free to print that sheet and write the values on it or just make a list from 1 to 14 and write them down then get a picture of that.
Lastly just make sure you note the orientation of the connector. Use the wiring colors to orient yourself so that we are not recording voltage incorrectly.
I get that you have done this, but I would not like to point you to a module if that is not the issue. Thanks
