Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
The dealer is your best bet for this, but you need a better tech to diagnose this issue. The need to do drainage tests again and bi-directional tests with their scan tool to see where the problem is at. Seeing that this can be a potential danger hazard, the service manager needs to get involved too.
