    Default YAY! New failures!

    SOOOOooooo yesterday the door locks decided to quit working and the door ajar light stayed on. Then they miraculously fixed themselves. Today they are out again, the TPMS is going nutz, and the interior light wont turn on. Rear locks wont operate even when physically pulled. So I have a tudor 4-door. Anyone know WTF is going on here? Car runs fine.

    Check yo grounds. You have to have something messed up somewhere for it to be acting that way, especially across multiple systems (locks, interior lights). A blown fuse would have taken out all 4 door locks, not just 2.

    +1 check the grounds... specifically the ones behind the driver kick panel that are bolted to the body. Then the quick connect strip next to the steering column if it has that batch.

    YEah, the power locks are not working at all along with the interior light, and the TPMS light just stays on. Also the Odo/Trip fades in and out, sometimes when I whack it it pops back into full brightness, but the other stuff just stays off. Also the driver rear door lock is stuck. Cant manually pull it like the others...

    Check your door for good ground, given the tpms, locks, and light is affected, it all has all or some control from the DDM. Or if you are lucky, a connector on the DDM has somehow come loose.

    Old post but is there a BCM on the Panther. After searching numerous times for a bad ground or blown fuses, nothing. The blend door actuator was replaced prior to all of this starting. I cant find any wiring diagrams (without paying north of $300 bucks for a pro level subscription) ans all the DIY sites don's seem to shave a GS trim level diagram.

    The BCM is the DDM (drivers door module) on the panthers. That said, many grounds are behind the passenger kick panel (among them the instrument cluster ground terminates on the passenger side), given you had a blend door actuator done at the time, the kick panel has to come out, and if whoever did the bda was hamfisted they could have broke something in the process. If you pull the kick panel the ground points will be immediately apparent. And while your there, pull the glove box and visually inspect the harness as far as you can, note: there is a harness that is routed directly into the upper corner (closest to the door) that is secured/has a channel to sit in, in that location, you will not be able to move it with the dash bolted to the car as the dash traps it. Checking grounds, find yourself a pinout for the ddm and do a continuity check between those points and ground to save the bigger headache of trying to reach things that may be inaccessable.
