1997 TOYOTA 4RUNNER; REPLACED SUNROOF MOTOR AND SWITCHES FROM SALVAGE; SUNROOF WON'T OPEN,MOTOR FOR TILT AND OPEN-CLOSE WORKS MOMENTARILY THEN A RELAY CLICKS SWITCHES OFF FOR A FEW SECONDS,THEN ON AGAIN. HAVE NEVER HAD SUN ROOF WORKING, VEHICLE BOUGHT 2 MONTHS AGO. IS MOTOR DRIVE GEAR ALIGNMENT AN ISSUE?? CAN I OPEN SUNROOF WITH MOTOR AND HAND?? OPEN BY HAND?? WITH MOTOR OUT?? JUST TO MAKE SURE IT SLIDES OK?? WHAT OPTIONS DO I HAVE??
