1968 DEVILLE WINDOW PROBLEMS

HI I HAVE A 68' DEVILLE AND THE REAR WINDOWS STOPPED WORKING. I BOUGHT REPLACEMENT MOTORS FOR THE WINDOWS FROM ALLIED AUTO PARTS. THEY SEEM TO WORK OUTSIDE WHEN CONNECTED BUT WHEN ALL HOOKED UP IN THE DOOR PANEL IT WON'T GO UP, IT LOOKS LIKE IT'S TRYING BUT DOESN'T HAVE ENOUGH POWER I ALREADY EXCHANGED THEM THINKING MAYBE IT WAS THE MOTOR ITSELF BUT THE SAME THING HAPPENED.
 
RIGHT WINDOW: WILL GO DOWN IF YOU PRESS AND HOLD THE DRIVER SIDE SWITCH TO EMERGENCY THEN HAVE SOMEONE PRESS THE SWITCH IN THE BACK UP OR DOWN. IT WILL ALSO GO UP BY USING THE DRIVER SIDE SWITCH BUT WILL NOT GO DOWN USING THE DRIVER SIDE SWITCH. BUT NEITHER WILL WORK UNLESS ON EMERGENCY?
 
 
LEFT WINDOW: SAME THING WITH THE EMERGENCY SWITCH. YOU CAN SEE THE MOTOR TRYING TO MAKE THE WINDOW GO UP BUT CANT DO IT.
 
MY CADDY WAS HOLDING WATER DURING THE RAINY SEASON I FINALLY DRILLED HOLES UNDER THE BODY TO DRAIN.
                              
                                          CAN SOMEBODY PLEASE HELP ME????????

I'd be checking all your grounds on the car. Take the connections apart and sand down the connection and then use dielectric grease before you retighten connection. This will take a while but will pay off in spades. Good luck.

THANKS FOR YOUR REPLY. COULD YOU PLEASE BE MORE SPECIFIC ON WHAT "CONNECTIONS" YOUR TALKING ABOUT. I'M THINKING THAT SOMETHING MAY BE WRONG WITH THE EMERGENCY LOCKOUT SWITCH BECAUSE THE WINDOWS IN THE BACK WILL ONLY FUNCTION IF ITS PRESSED TO THE EMERGENCY SIDE BUT IT TAKES TWO PEOPLE TO ROLL DOWN THE RIGHT SIDE WINDOW. I CAN BY ONE FROM A CADILLAC JUNKYARD FOR $50 BUCKS THINK ITS WORTH IT? THANK YOU
