E39 - The never ending love/hate relationship

[BSDeeZNutZ]

I spent the entire weekend tearing the intake manifold down to replace the valley pan. Saturday I performed the teardown, replaced the valley pan, cover, intake manifold gaskets, and dropped the manifold back in the car. Sunday, I finished assembling the various plumbing and electrical connections. Double checked everything, and after several attempts, get it started. After several anxious minutes the idle finally smoothes out and everything starts running good.
I take it out for a ride, a much needed cup of coffee, and a sixpack of decent german beer.

When I get back home I back it into my garage, throw it in park, and roll up the windows.
The right rear window gives that dreaded "POP" and stops dead.
:mad

While I have the replacement regulator sitting in the tool cabinet waiting for the day the rear passenger side goes, why does it wait until I fix the vacuum leak?

It comes in three's. Had to repair my sunroof which took all weekend, get everything back together and my fuel pump craps out on way to work on Monday. Get that replaced, now I am working on getting rid of an electrical gremlin. Hoping it is just a low cell on the battery or something.

what exactly was wrong with her in the first place?

Sounds about right, just when you think you have everything up to date...

P1175/P1174 codes started this whole project.
It was a vacuum leak that was pretty easy to diagnose, but not as easy to fix.
The manifold gaskets were shot (front, rear, and bottom all were cracked).
Front, rear, (CCV & gasket replaced before I did all the rest of the work) and bottom profile gaskets all replaced, along with every other gasket in sight, and that damned vent tube that feeds into the CCV.
If you're gonna go that deep, you might as well do the valley pan too.
I cleaned out the TB & ICV and checked all vacuum hoses and connections during reassembly.
