Ofton when i press my hand held keypad to lock my truck doors on 2008 titan the windows roll down??? any ideas on problem....

Most cars these days have this designed into the window system. Its a safety issue and I'm afraid there may nothing you can do. If there is more window track below the bottom of the glass, look for stops bolted or rivited in the track. If so, you may be able to move them down. However, this is dependent upon the drive mechanism, which may also limit window travel.

I am assuming that the switch from the drivers side will roll the window down and up for all windows, so this is going to be a worn out or defective window switch in the passenger door. These are quite easy to change, and can get the part from the dealer for usually at or around $50.

The armrest cover will pop up where the switch is with a little effort, flip the cover over and remove the plug to the switch. The switch has usually 4 tabs that will need to be pried gently back and the switch housing will release. Install the new switch housing, attach wire plugs, and it's plug and play! This will correct the problem.

Window and lock switches use a small plastic piece that presses down on metal tabs. These plastic parts wear out, or I have even seen them get hot and melt if pressed and held down by kids playing with the window buttons.

Hope this helps, let me know.

Look for water getting into a connector, usually in the wiring in the drivers door. Remove the door trim panel & check the connectors. report back

wires go thru the boot. most likely broken wire from the switch. if the window works with the key in the door

Verify the hand-held transmitter is operative.
Prepare for programming the universal transmitter by erasing all three channels (hold down the two outside buttons until the red light begins to flash [20-30 seconds]). Release both buttons.
Select one of the three universal transmitter channels to be programmed by pressing the desired button
Hold the end of the hand-held transmitter 25-51 mm (1-2 in) from the front surface of the universal transmitter so that the red light can still be seen
Use both hands to press the hand-held transmitter button and the desired button on the universal transmitter. Do not release either button.
Hold down both buttons until the red light on the universal transmitter flashes, first slowly and then rapidly. Release both buttons when the rapid flashing begins. The universal transmitter has successfully learned the new frequency signal and can be used in place of the hand-held transmitter(s).
If the hand-held transmitter appears to program the universal transmitter but does not open the garage door, the garage door opener may have a code protected or rolling code feature.
To operate, simply press the appropriate button on the universal transmitter. The red light is on while the signal is being transmitted.
IF THE GARAGE OPENER HAS ROLLING CODES---
program as above then------
Train the garage door opener receiver to recognize the universal transmitter.
Remove the cover panel from the garage door opener receiver.
Locate the training button on the garage door opener receiver. Location and color of the button may vary by garage door opener manufacturer. Refer to the garage door opener instruction manual or owner literature.
Press the training button on the garage door opener receiver for 1-2 seconds.
Press the programmed universal transmitter button for as long as the universal transmitter red light flashes (1-2 seconds). Release the button and re-press the button to confirm that the universal transmitter is trained to the receiver.
The garage door opener should recognize the universal transmitter.
