2004 Chrysler Crossfire. I know the locks are an issue with this car. I have searched, did some reading, but didn't find anything that quite matched my situation. So here we go:

Locks: will unlock, won't lock.

Key fob: lock button will not lock driver's or passenger's lock, or fuel door or trunk. If doors are locked manually, unlock button will unlock them both with 1 press. When unlock button is pressed, you can hear the vacuum pump in the back activate and unlock. When lock button is pressed, cannot hear it activate. You can see the lights flash from the outside when either button is pressed. But only unlocking/locking happens with unlock button. Can't tell if unlock will unlock the fuel door or trunk due to not manually locking them or knowing how.

Central console lock/unlock button: nonfunctional. Lock does not lock anything. Unlock unlocks nothing.

I replaced the vacuum pump in the trunk today. Previously, nothing would lock or unlock by either the key fob or central console button. Replacing the pump at least got me to unlocking. Replaced the number 9 fuse, no change. Checked the trunk area where the pump was located. It's bone dry.

So...any idea where to go from here?
