Bay door locks

All right..I've searched to high heaven for an answer to my problem. Maybe someone on here can offer some advice. I have a Monaco Executive 45PBQ with auto bay door locks. The bay doors can be locked either by pressing the key fob remote or pressing 555 on the combo by the door. Pressing the other button on the remote unlocks them. You can also do so by entering the correct code in the code reader. My issue is this...

Last week the driver's side bay doors decided they wouldn't cooperate with the passenger's side. When I depress the button on the key fob, the passenger side doors open like they should, but the driver's side ignore the command. Using the key pad and I get the same result. I've checked all the pin switches on all of the doors and they appear to be working correctly. I've checked the breakers, the GFCIs and all of the fuses, front run bay, rear run bay and closet. All fuses checked ok.

Anyone have any ideas? The keys open the bay doors and lock them as they should. That said, I'd like to get the remote locks working again if possible. This only affects the driver side of the coach. TIA...

    Have you ohm'd out the coils to see if they are intact?
    DW's FOB unlock button jammed a few years ago causing all of my lock solenoids to burn out, fortunately in unlock mode. Had to replace them all..

    Dennis you said checked all fuses... FRB fuse is labeled DS ACT and PS ACT. These are the fuses for the door locks. ???

    Any chance the programming got erased or changed on the driver's side? Is it a dip-switch programming or RF/IR programming? Maybe a temporary loss of power to that side? Not familiar with the setup, but just guessing that there may also be a small button-cell battery on the remote locks.

    Since all of one side is not working... that side is not getting power. As Chuck suggested, probably the DS ACT fuse and hopefully it does not blow again indicating a short somewhere, even one of the solenoids.

    Dennis,

    One time I had a similar problem with my bay door locks and my remote. I used the key to unlock the bay door where all of the fuse blocks and electronics are located (in my case the left front) and unplugged the controller for the alarm and locks hoping to reboot the system. It worked. No problems since.

    Good luck and safe travels.

    Thanks for all the suggestions so far. I looked at the diagrams in the Monaco manual and it indicates the circuit goes from the PS front bay to the rear of the coach and then over to the DS. However, it does not show the 'switch' on the engine hatch. That switch has been broken for years and appears to be one of the plunger style switches. I just wired that switch together and it's worked fine until now. I've checked the continuity thru both sides and it checked ok. One thing that happened the other day was in locking the coach with the key pad, both sides locked but only the passenger side would unlock.

    I'm also at a loss as to where the fuse(s) marked DS ACT and PS ACT are located. Would those be in the front run bay? TIA...Dennis

    No dip switches..everything goes thru the key pad which is programmed. That said, the key fob works independently of the key pad which would indicate the 'issue' lies within the wiring of the coach. Thanks for your input....Dennis

    Yes on the passenger side. Only sometimes on the driver's side, and only in lock mode. Not in unlock.

    Dennis, I honestly don't know much about that system as it was probably the exact same system that we had on our Dynasty. Since it hasn't been mentioned, I'll say it. I was always told that the locking system had a controller either behind a panel at the passenger side dash board or behind the storage compartment at the passenger seat. Do you think that controller might be shorting out?

    This is just a thought as my thimble runneth over.

    Safe travels,
    MM.
