I had a Saab 95 (the station wagon version of the 96) with that engine. Absolutely bomb proof motor. Wish I could say the same about the transmission.

The problem with these old cars is that all the glass is inset deeply into the body.

Solvable problem. Picture a lead sled Merc time attack car. Smoked gray plexiglass from the drip rail to the beltline crease, wall to wall on the door and from the B-pillar to the end of the drip rail over the quarter-window.

Then a driver's window like this:

Also I may try to tape the back of the front door glass to prevent air leaking into the door and see if that helps. I'll try removing the mirror too.

The problem with these old cars is that all the glass is inset deeply into the body. The windshield has bulging rubber and stainless trim around it too. I wish we had access to a wind tunnel we could use to work on these problems

You'd be looking at either the A2 tunnel in Mooreville,NC (@ $480/hr for the 1st 2-hrs),or DARKO,Ogden,Utah ($500/hr).

Wow, that's expensive, but I'm glad to know that the service is available. Thanks!

I thought of a diagnostic tool for you.
stick on window sealer for your house it's meant to be put on the inside of your windows to reduce drafts. Try to find some that is a push to stick type then you heat it with a hair dryer and it shrinks. Do just the inside window to test the felts... if not tbere then start covering suspect places. No idea how well it sticks
Just an idea.

Thanks! I'll look for that at my nearby Home Depot

If all else fails get some noise cancelling headphones

You claim the noise also exists on the passanger aide.

Get some one else to drive while you hunt around on the passenger side.

Thanks, I have been using my noise-cancelling headphones on those long high-speed trips for some time now

There is NO doubt that the same wind noise is on both sides. It is loudest at the "A" pillar and at the lower part of the door glass just above the door handle

Guess I'm getting old, loud sounds really bother me
