94 Caravan Le. electrical problems

have a 94 caravan le. i just bought this vehicle and come to find out its got some probs. the alt gauge isnt working (i checked fuses all good) also the electric locks and back door hatch switch doesnt work,the electric mirrors dont work, the interior lights dont work. I've checked all fuses i could think of and bulbs and none seem bad. also made sure all wires were hooked up to everything and the all seem fine also. if any one has any info would be much appreciated thanks also it has a keyless remote for the doors and back hatch and it also wont work.

There is a common fuse to every circuit you mentioned, I believe it's the IOD fuse in the power dist center under the hood. Fuse may be ok, but the connection to the PDC may be bad, which is fairly common to the vehicle. If you don't have power to the door lock switches, mirror switches, liftgate release switch, then that's probably your culprit.
