My power locks quit working at the same time my door ajar light came on plus my automatic lights only work on the parking lights. Its a 2006 f150 4x4 super crew cab is there thing i can do be i take it to a dealer

 

Chck fuses and relays

 

Could be fuse but my guess would be something gone wrong with door switch.

 

I have checked all fuses and relays, i understand there is a vss system that runs all this.i wanting to know is what activates the vss is it the door switches, where you start troubleshooting

 

vss = vehicle speed sensor, has nothing to do with the door locks. I would disconnect the battery ground cable for no less than 15 minutes, it may reset.

 

Yes, great advice.

I'm so used to working on my '80s P-cars that I tend to forget about all the computers involved in nearly every aspect of a modern vehicle.

Unhook battery as suggested above and re-evaluate symptoms.

 

I think there are threads about the wire in the body to door loom breaking causing these symptoms. May search it a little deeper and find your answer.

 

Thank you all for info. I was lead to believe the vss was the vehicle security system. Im goingto try ddisconnecting the negative cable and reset everything
