You may need a clip lead extension to get enough length to get to a good ground. Besides, having a clip lead means the ground (black) wire of the meter is held in contact, so you have hands free to probe various pins. DO NOT believe your meter until you have measured 12 volts at a known source. That way, you know your meter setup is right. Also, keep in mind that clip leads have a short life span, so verify them often by measuring a known source of 12v. I often dasiychain several clip leads in a string and tie to the battery ground post. That way, if I measure voltage on a ground point, I know my ground is no good.

Thanks pizza, I used a ground wire that’s in my trunk for my subwoofer to test. it’s worked fine in the past so I assume that’s a good ground. From what is going on I’m still getting 0v on pins suggested in my manual so now I’m guessing I have some failed wiring somewhere? Kind of hard to believe considering this only broke from my rear window seal being bad..
