Can the window motor be bad if you can hear it running?

Open it up and investigate-could be offtrack-

Can the motor or gears be worn out? It looks on track but seems to try leave the track going up.

THE '86s AND IN THAT ERA HAVE SORTA A TRANSMISSION ON THE END OF THE MOTOR....MY DAD'S T-BIRD'S WINDOW MOTOR SPUN W/ NO MOVEMENT OF THE WINDOW

I SNATCHED IT OUT AND TOOK IT APART, THERE WERE 3 PLASTIC PELLET THINGEES THAT "CUSHIONED" THE TORQUE ACTION, INSIDE THE TRANSMISSION. THIS KEPT FROM "CRUNCHING" STUFF WHEN THE WINDOW HIT TOP OR BOTTOM OF IT'S TRAVEL.

THE PELLETS WERE CRUMBLED INTO LITTLE CHUNKS...SO THERE WAS NO TRANSFER MOTION IN THE TRANSMISSION

WHEN I DISASSEMBLED IT, I WAS CAREFUL TO SEE HOW IT WOULD GO BACK TOGETHER

I EVEN REMOVED THE ARMATURE AND SANDED THE BRUSH RIDING SURFACES

I REASSEMBLED THE WHOLE THING

I REPLACE THE PELLET SCRAPS WITH THREE OF "JUST THE RIGHT SIZE" BALL BEARINGS.....FROM A BICYCLE'S REAR WHEEL BEARING ASSEMBLY

I'M REALLY GOOD AT "MacGYVERING" MIGHT NEAR ANYTHING!

I FIGURED WHAT COULD IT HURT TO TRY.....WAS GONNA NEED A NEW ONE ANYWAY

I FOUND YOU DON'T TIGHTEN THE PACKING SCREW TOO TIGHT ON THE END FOR THE ARMATURE....I TESTED 'EM WITH JUMPER WIRES OFF OF THE BATTERY BEFORE I RE-INSTALLED 'EM

THIS WORKED FINE!.....A MONTH LATER THE OTHER SIDE WENT OUT...I STILL HAD A BUNCH OF BALL BEARINGS LEFT!

NEW MOTORS, BACK THEN, WERE $115 A POP!!!

THIS IS THE MOTOR AND PRICE NOW

LOOKS LIKE THEY MAKE A "KIT" NOW---THE PELLETS ARE INSIDE THE PLASTIC GEAR, THAT THE METAL GEAR IS SITTING ON IN THIS LINK
