Where is the seat senor that is connected to the air bag light located on a dodge caravan 2007 3.3 liter ?

check fuses and relays their are different locations for air bag sensors and their is also seat belt sensors and seat switches [check the connections under the seat ]---their are sensors under the front bumper behind the valance by the radiator support also if air bag curtains passenger side between inner fender, door and door pillar the following links have information or what to look for and assist in solving your problem the recall doesn't cover your vehicle but it pertained to the passenger air bag problem as well as the 05 posting

Next to the thermostat housing. It has 2 wires connected to it.
Follow the hoses, they will take you right to it.

the computers cant talk to the pcm that controls the engin

There is some sort of diagnostic code stored in either the ECM(engine computer) or TCM(transmission computer).There are many sensors and solenoids and other data parameters that can cause a codes to set other than just the oxygen sensors.You will need to have the code(s) pulled to know where to start.

If this happened over a short period of time. have the catalitic converters checked. They're clogged, insuffient air flow. Also check for codes. just because the light is not on doesn't mean there is not a code.

their is a wiring coinnection under the seat then this goes to the bottom of the seat belt explosive piston where their is another connection ,just clean all connections and smear some vasoline on the electrical connectors ,works about 80% of the time without the need for a OBDII computer reset

i may be mistaken on if this applies to your model year but if the rear wiper does not work then check the fuse for rear wiper and replace if blown. make sure rear wiper switch is off and wiper is parked.if air bag light goes out after a few seconds then the rear wiper motor is bad causing fuse to blow. air bag module gets power for its fuse through wiper fuse.if wiper is not parked then fuse may blow when you turn yhe key on.you have two choices. replace wiper motor or remove tailgate door panel and unplug the motor

I have a 2002 jeep grand cherokee Limited and Had similar problem. Found out that a wire/connection harness had gotten cut under PASSENGER seat.from seats moving back and forth. It's part of the airbag system, it tells airbag system if seatbelt is fastened and if occupant is in seat. Since the wire is broken, it can't report back to air back system and activates the light. try this, hope it helps.
