My rear doors will lock but will not unlock all the time, this is by the remote or the switch on the inside. Front doors work fine, press button once drivers door twice should be the rest. If you keep trying to unlock it may finally unlock. Thanks for your help in advance.

It's probably the relay for the rear doors. Switch the front relay with the rear and see if problem switches to the front.

I think it is in the box under the hood.

I found a drivers door relay and passenger relay in the fuse panel beside the dash and switched them and so far it works maybe just a bad connection on the relay
