The pneumatic door lock system is unresponsive- makes the “beep” in the locking direction but no key resistence in the unlock direction. So, can’t open the hood or troubleshoot pump or wiring. Anybody got an idea how to unlock the door short of breaking the window? I can get into the trunk, but that’s it.
