Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
The test with soap and water can't find your leak. You need to attach a smoke machine to the air lines and this will find it.When you see the smoke escaping, you found the leak. It's working electrically or it wouldn't pump back up.
Okay, then attach your scan tool and go to the body module to do bidirectional tests. This will show you what sensors/switches are being activated and de-activated.
Thanks again and please remember to rate me 5 stars and keep this ;link in case you need me again later on.
If you are satisfied with my answer, I would greatly appreciate a 5star rating now and I will still assist you after you have rated metoo if another question pops up. I don’t get credit for helping youuntil you rate me.Thanks again, Ron
You're missing something, with the information I gave you so far, this issue should have been found by now. I'm not sure what went wrong or got missed, but I suggested scan testing and smoke machine testing and one of those tests would have revealed the issue.
I don't know what tools you have used or your skill level, and I sure hope this doesn't affect my 5 star rating. I told you valid truthful information.
