Door lock switch - 9/26/2006 11:13:33 PM    Huhhhhh Posts: 11 Score: 0 Joined: 9/26/2006 Status: offline Anyone know what may cause the door lock switch on the driver and passenger side to stop working while the key fob and keypad still make it work?? I have a 2006 F-250 XLT superduty diesel. _____________________________ 2006 F-250 SD/CC 6.0 Diesel 6 inch ProComp Stage 2 Lift 325/65R18 ProComp M+S X-treme A/T Delux 500 Bulldog Remote Start 8500K GP Thunder Xenon/Plasma Headlight & Foglights 2000 lb. wench in bed to pull in dirt bikes, Elk, Deer, ect.

Or just remote access... _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to Huhhhhh) Post #: 2

The lock switch started acting funny when it would pop back up after I locked it while the door was open. It did that for about a week then went dead. The passenger door does the same thing. Dude your awesome, how do you know all this stuff? (in reply to Hayapower) Post #: 3

If both the panel switches prove out dead, then I'd suspect the VSM (Vehicle Security Module) as it houses all the relays for Park Lamp, Headlamp, Door lock/Drivers Door Unlock and is micro processor controlled transceiver in one unit.. Or circuits/connectors leading to it.. The VSM needs to see a command for ‘lock and/or unlock’ at the switch/s via the VREF/Ground and then activates the lock actuators/motors for the given command...Reference power to the switch panel is provided through the VSM. Being that the key pad and fobs still work, would lead me to think it was a processor problem.. Could be any of a number of causes, but a test at the switch would give a 'good' point as to a direction to go… Do you have a DVOM?? Have you contacted Ford for a warranty visit? < Message edited by Hayapower -- 9/27/2006 8:43:30 PM > _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to Huhhhhh) Post #: 4

Thanks for all the help. I'm going to try and post a pic. of the truck. Let's see if it works. Thumbnail Image Attachment (1) (in reply to Hayapower) Post #: 5

A DVOM is a digital volt ohm meter.. Without a scan tool to check for stored trouble codes/system failures for the VSM, a 'quick' test at the lock switch for voltage with a DVOM would be an indicator as to if it were related to the module or its circuits, or if power was at the switches, another avenue to go.... Shouldn't be a huge problem since it's a constant, and not intermittent issue... _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to Huhhhhh) Post #: 6

RE: Door lock switch - 10/1/2006 11:19:28 PM    Huhhhhh Posts: 11 Score: 0 Joined: 9/26/2006 Status: offline OK, I disconnected the remote start from the door locks and got voltage to the switch. When I lock with the drivers door switch all the doors lock, but then the drivers door pops bock open. Same thing happens when I lock with the passenger switch. If I lock the drivers door then unlock with the switch everything unlocks normaly. Would this be a switch problem or relay?
