Power windows in 2003 Sierra

Installed a Viper 791 in a Sierra 2003 and everything works fine.  But I cant get the window roll up to work. Im using two 529t, connected between the switch and the motor but i cant get the window to move.

I know the modules work couse i can hear the relay click when I arm the alarm. Im using two modules one for each window to roll up and down,  customers is coming back on sunday and  I still dont know what could be wrong.  any ideas will be welcomed.

You're best bet is always to wire these AT THE MOTOR.

I'm guessing that this car likely already had the factory feature where you could tap the swtich and the window would roll all the way down (and maybe up too).  If this is the case you MUST wire the 529T as close to the motor as possible.  The 529T "listens" for motor noise (resistance) to know when to STOP rolling the window up (or down).  If you have connected between the SWITCH and factory CONTROLLER, you'll experience symptoms like you're seeing.

The clicking sound that you hear is the relays inside the 529T.  If the windows are not moving it's likely that you'll need to try to reconnect the 529T at a different location in the door (closer to the motor).  The 529T and 530T will not work "through" your factory controller.

Hope that helps... Good luck! 

yes the windows will go down and up with one tap of the switch. now im about 2 inches from the motor and i have connected the modules the regurlar way but they are in the kick panels with 10 gauage wires for ground and voltage, the clicking of the relays only means that the 529 is working but i dont know why the windows are not moving,

both wires at the motor will test 12 volts at the motor no matter which i press the switch,  i don't know that else to do.

thanks for your help.
