Good news is these units are relative easy to find in the junk yard. We took apart one last week and the o rings were hard as rock. They literally broke off when we pried at them.

Thanks NavySeabee for the O-Rings.
Anybody in here got some spare silicone O-rings in the 007 size needed for the repair that they could send my way? I've got the typical problem: air out of defrost vents only.

Guys, if you sent me your mailing address for o-rings, I can't find them!!
Somewhere in this house is a package with about 70 o-rings. I must have put them away somewhere they'd be safe. It's driving me nuts! Don't know where else to look and my OCD won't let me quit looking!!
Sorry for the delay.

Ingsinve had the out the defroster syndrome for some time. It used to switch automatically. So I thought it was normal. Guess not after reading this thread. My question is, can you use rubber or Viton orings? And if not would anybody like to toss some this way. Thanks

Never mind on the orings. I got some on the way. I checked my original orings and all seem pliable. Is there a certain way to vacuum check the solinoid (that doesn't look right) case

I want to thank everyone who contributed to this repair. My 2003 Crown Vic LX (136k) had the same problem, (the airflow switching to the defrost vents under low vacuum conditions) and this procedure worked like a charm. The O-rings in my unit were not broken but seemed harder than the newer #007 ones I replaced them with. The whole repair took about an hour and was made even easier thanks to the excellent notes.
If anyone needs some O-rings shoot me a msg and I will send out the remaining ones that I have.
Too all those that have contributed to this solution, You are AWESOME! I can finally get the A/C out of the panel instead of the defrost. And for less than $15 bucks vs. the $900 I was quoted. Thank you so much.
I'm gonna need to do this mine started do this defrost blowing for a few mins then vents.. hate it.. but I can't seem to find the orings at autozone or oreilys.. online order I guess
