    Only the driver's side is not working this did not seem to help. The passanger side is still working fine. The drivers side stays locked in place.

    Sorry for the delay its been a busy week. I am going to look into this this week end. Have a basic knowledge of electrical and the other side is working.

    Where should I start - check power to the motor and back up. Where do I check the motor and how many volts (12?) or just check for power. Is there some kind of relay or sensor that knows the door is open that could be dirty or stuck?

Is it physically broken? For the board there is really little that you can do with it. You can inspect the brackets and the mounts to which the board is attached to and check for loose connection or broken ones. I would discourage to attach broken pieces together with industrial glue as they are prone to accidents. You may have to replace parts or replace the entire set.

More than likely you accidentally disabled the feature if you have already checked the fuses and they are good.
Your owners manual tells you how to re-enable the power deploying running boards .
I'll paste a copy of the directions for you :

To enable/disable the power running board feature, refer to the Message
center in this chapter.
• When this feature is disabled <OFF>, the running boards will move to
the stowed position regardless of the position of the doors.
• When this feature is enabled <AUTO>, the running boards will move
back to the correct positions based off of the door positions.

(Message Center )

Setup menu
Press this control for the following
• Reset to English (if in another
• System Check
• Oil Life
• Units (English/Metric)
• Autolamp Delay (if equipped)
• Easy/Entry Exit
• Air Suspension (if equipped)
• Autolock (if equipped)
• Power Liftgate (if equipped)
• Power Deployable Running Boards (if equipped)
• Compass Zone (if equipped)
• Compass Calibration (if equipped)

Power Deployable Running Boards (if equipped)
This feature automatically deploys the side running boards for easy
entry/exit from the vehicle or for cleaning.
1. To disable/enable the power
running board feature with the
vehicle in P (Park), select this
function from the SETUP control for
the current display mode.
2. Press the RESET control to select the running boards setting as
• AUTO: the running boards will automatically deploy when a door is
opened and automatically retract when the door is closed,
• OUT: the running boards will remain deployed regardless of the doors
being open/closed. This setting can be used when washing the vehicle, or
accessing the roof rack. The running boards will stow and enter AUTO
mode when the vehicle speed exceeds 5 mph ( kph),
• OFF: the running boards will remain IN regardless of the doors being

Let me know how this turns out.

    Well, then you either have a burnt out motor or bad wiring that you need to check out. This may be hard for the average person to check if they have no electrical knowledge.

    Yeah, the best thing to do is start at the motor and work your way back to the car battery, just seeing where the voltage ends or doesn't show up. Make sure when you are checking is when the running board should be moving so you may need to constantly open and shut the door. There is no sensor other than the doors being open, check the metal contacts on the door, try cleaning the door where it meets the frame of the Navigator. Good Luck.

Why does the control board gets hot after abt 30mins of ignition and the injectors stop working hence the car cant move?

engine wont start, or run, moving is way beyond that.
now a wild guess, he PCM gets hot.
there are only 2 causes (yes, i repair them and other modules (boards)
1: battery voltage too high (alternator went berserk)
2: ECU outputs shorted,

just 2.
to if battery is ok
then remove all ecu outputs.
1: all injectors, ok now? no hot?
2: all VSV solenoids.
3: all relay off PCM (fuel pump relay )
4: ISC connector pulled.

no engine stated, of the 6 or more
nor country, yes, they run unique PCM from ours (laws)
this is USA site so, no country ,hard to help you.

Retractable running board not functioning

Remove the running board and pry down the bracket holding the board to the motor. (I used a crow-bar) This will rotate the mechanism slightly and the board should work again. I did this a few months ago because the board on the driver side stopped moving. It has been fine ever since.

2002 gmc yukon radio and wipers and windows stop working the I can hit middle consal and it might or might not work for a will Help

Power for those devices is provided from the retained accessory power which is controlled by the BCM (body control module) which is in the console.I had the same problem with the radio, wipers and windows all stopping. I tried running the diag procedure for the BCM but couldn't get in to run. I then read online about a loose connection in the BCM, so I took the 4 screws out of the console, got access to the BCM and removed it. inside is a small circuit board. On the back of the circuit board where most of the soldering is, there was a bad connection to a relay. Re-soldered the connection and the problem went away.
