Been a while since last post - cheers to all! I have a quick question, my doors are locking fine (a little slow). During driving I'm hearing the vacuum motor cycling - I take it it has a leak. Where is the most common area for a leak on these lines.

Take the back off of the front seats and listen to see if your leak is from either the Y connectors or from the bladder itsel. My passenger seat bladder had a seal break and I had to fix it.

Or one of the lines underneath the seat. That's where the leak was in my 43

I've taken the seat backs off before, I'll check under the seat next - any other ideas?
