Yesterday I took my van to the Chrysler dealer to ask them again about the door latches automatically firing at random times. They had already spent a few hours trying to solve the problem. I asked if disabling a fuse would help, but owners manual showed no fuse for the locks. The mechanic found another section that identified fuses in a box inside the engine. One was for the latches. Disabling it worked, but turned off the airbag mechanism. We put the fuse back in. There are two fuses in the engine fuse box for airbags. Probably one for each airbag.
Is it possible that the manual is wrong about the latches fuse? I would think not, but that suggests the problem is somewhere else. Maybe something to do with the fuse box itself.
P.S. my problem on this and others got started when rodents got into the engine compartment. The only thing no longer is the latches. It's not likely I'm going to continue with repairs. For the moment, I'm just going to take the mechanics suggestion that the problem might be weather related, dampness, perhaps. In the mean time, I plan to use the van once a week just to keep it happy, and some other local driving when I need to use it to haul big items--the back seats are stored in the garage.
