Do the rest of your doors open ? Does the passenger side door lock/unlock ?

Location would help to guess if the issue is cold / ice.

I could only lock it from the passenger side door, that locked all the doors. I tried to unlock the car 15 min. later and could not unlock either door. The key turned in the locks but did nothing. I had to enter the car with a piece of thick wire to pull door lock up, that unlocked all the doors. I checked the vacuum pump under the back seat seemed to be ok.
Could there be something broken on both door locks?
Thank you very much for any advice on how to continue

No trunk locks on those critters?

With a 15 minute vacuum bleed off you have a leak in your vacuum system. Your friendly easy to use Mityvac should make short work of it.

Drivers door may have a bad mechanical but obviously your vacuum system has an issue.
