Door light, radio, and automatic door unlock does not work on my 1994 MPV what could it be the van turns on but only when its on do all the doors unlock at the same time.

Daughter had same problem on '05 T&C. Neighborhood mechanic searched Internet and found 80-90 others with same problem right around 40,000 miles. Free solution was to pull yellow 20A IOD fuse in right front corner of fuse box under hood, wait 10 seconds, then reinsert fuse. Should solve problem as long as you don't lock doors with FOB. You can unlock doors with FOB, but apparently locking with FOB causes the problem.

Permanent solution is to have dealer reprogram computer for around $50 which is what my daughter chose to do because of inconvenience of not being able to lock doors with FOB when getting baby/carseat out of vehicle.

you need to take it to the dealer and have them check the bcm for codes.... also have them check to be sure you have the latest software in the bcm.. its possible that you just need a software update... there are several TSB's covering the concern you have..... it can be a very simple fix with software or even a stuck lock switch may need to be replaced... without the proper diagnostic codes being read from the bcm all that can be done is guessing..and that can be expensive...

Most likely is a fuse. There is a fuse box at the end of the right side of the dash. Open front passenger door and there is a cover that says fuses on the end of dash. There is also a fuse box located under the hood at the right front of engine compartment. It should have a cover with a round knob in the middle of it .Unscrew the knob to remove cover.

The motor is shot. It works a little and overheats, replace the motor . Same thing the the lock acuators. The are trying but have lost the power to move the locks. May as well replace them while the door is apart.

sounds like the lock rod fell off. Take the door pannel off and reatach it
