All 4 automatic door locks, truck lock and gas door lock quit working from the key fob and internal buttons. I checked all the fuses and relays and all are in good shape. Battery in Key Fob is new, so is not the problem. Rear Window defrost also quit working I think about the same time which leads me to believe it is something electrical but could find nothing wrong. I fear this is going to be one of those mystery diagnostic checks that costs a bundle. Any suggestions?
I checked all the fuses and relays and all are in good shape???????
Did you check the correct one's ,that's the question ? And did you use a voltmeter or test light to check across the correct fuse's ? And how did you check the relay's ????? Videos on youtube on how to test a relay ! And using a wiring diagram or power flow diagram that shows all componets of the none working systems ., Plus you need to know how the thing's work . Data communication network is involved in the working of these thing's , Data messages from module to module !
The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel Module (IPM)
• The Rear Integration Module (RIM)
Rear Integration Module (RIM)
The various RIM inputs and outputs are described in the corresponding functional areas as indicated on the RIM electrical schematics.
The RIM functions include the following:
• Automatic level control
• CIGAR relay control
• Class 2 communication requiring RIM interaction
• Content theft deterrent
• Fuel door control
• Fuel level sensor input
• Heated seat control
• HVAC blower control
• LK/CYL relay control
• Park brake relay control
• Rear defog relay control
• Rear park assist chime control
• Retained accessory power (RAP) relay control
• Reverse relay control
• Transmission shift inhibit
• Trunk release relay control
• Various controls for the interior lamps
Just looking at fuse's and relay's isn't enough ! Hooking up a factory scan tool an checking for DTC'S - diagnostic trouble codes in all the vehicle control modules is always the first step . Which fuse boxes did you check ? Do you know there is a fuse box under the back seat ?
Fuse Block - Rear
Left rear of the passenger compartment, under the rear seat !
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Your best bet , take it to the dealer !

bang on the door hard and put the window up.if there is a dead spot in the motor from lack of use,the motor will start.

Don't you still have a door key?Otherwise jack up the car and remove the engine under body cover.Between the radiator support and the engine are some hard lines.Remove the two brackets holding them,this will allow you room to get to the starter.Hook the red end of a jumper cable to the red battery cable that's connected to the starter.Black to a suitable ground and charge the battery.A battery charger is easier to use,use that if you have one.If jumping off a car make sure the cables are hooked to the dead car first and grounded to the engine not the battery of the car doing the charging.Sure hope this helps!

Check the fob battery you might need to replace it, The battery only has about a 3 year life
