Rear wiper motor

[Monewill2003]

I have a 2005 tahoe but i'm trying to put a 2004 suburban back windshield wiper motor in my tahoe. problem it is a littler bigger. on every site or forum most say it should work. I thought the motor didnt work at first, but it does the problem is when I clip it to the factory harness I hear a noise like its on and it is. but does not turn. but if I touch the metal contacts and the door and it works fine. Has anybody had this problem? Someone told me I might have a problem with my truck wires. and bad current running thru my truck.

PLEASE HELP ME OUT PLEASE

I did the same thing, it didn't work at first cause it had a bad connection. I cleaned and tightened the pins and it worked. as for the size, It does wiggle in place, but it's not nice.
