I have a 2002 F150 SuperCrew XLT with 5.4 auto. I noticed my autolocks stopped working a few days ago. The power door locks still work and everything else seems to be working normal. Could this be due to the brake switch going bad? TIA!

 

Wow, 90 views and nothing........

 

I'm not great with electrical, but possibly a fuse?

 

According to the owners manual there are three different ways:

"Deactivating/activating autolock
There are 3 methods to enable/disable this feature. One through your
dealer, the second with a power door unlock/lock sequence and the third
with the keypad.
Before following the activation or deactivation procedures, make sure
that the anti-theft system is not armed, ignition is off, and all vehicle
doors, liftgate and cargo doors are closed."

another thing to keep in mind, the doors don't lock right away, you have to be traveling above 5 MPH:

"This feature automatically locks all vehicle doors when the following
conditions are met:
• all doors are closed, and
• the brake is pressed before reaching 8 km/h (5 mph), and
• the ignition is in the RUN position and the vehicle is traveling more
than 8 km/h (5 mph)."

you should also verify fuses and wiring....

 

the fuse is working because there are other things on the circuit and they are working fine.

 

I finally fixed it..........TruckGuy24, you were right, fuse #29 inside the cab. The only reason I found this was because my OverDrive button quit working (apparently that stopped working a long time ago too). I looked up that fuse, 5A replaced it and my auto locks started working again.
