Thank you ! .

I can always trust the brain trust here to teach me new things ~ I thought there was only one vacuum element in the Coupe's seat back....

For the OP : the seat back locking vacuum circuit is all in blue and almost always leaks, it's a simple thing to cap it off under the hood for testing .

Vacuum leak testing is simple if tedious .
