Automatic door locks stop working. Have to use key on all 3 doors. Can get the front passenger door to lock/unlock with the key fob but it doesn't work on the other doors. Back door latch will not work with key or fob.
passenger door does not work with remote it moves a little bit but not enough to unlock the door I did have it fixed any tips on fixing it
Power locks stopped working. Took apart. Passenger side still doesn't work. Just have to open manually. Back hatch won't open. Not fixed.
door locks were fine first 3 months i had my astro van...then they started going haywire
up the dowwn while driving down the road...I had to remove the relay to stop i have no power locks.
In my 1985 van the sliding side door is where my power lock would fail to unlock occasionally. Solution has been to manually unlock it from inside and then attempt to open.
Lately the power door locks are acting funny. Sometimes they don't respond to the remote. Sometimes all the locks on all the doors lock and then unlock several times by themselves. But the worst thing is that when I push the button on the rear door to open it, all the locks immediately lock, including the one on the rear door so I can't open it. Any ideas?

Rear hatch door only unlocks on driver side, Passenger side does not unlock. How can I get it to open, so I can get to the top two screws to remove the trim ring, to access the actuator.
Front door locks have to be opened manually. Rear hatch wouldn't open but I fixed that. Push rod retainer was broken. Rear lower doors lock but I can't lock rear hatch at all.
