I had the right one on my 04 GMC go down and refuse to go back up a couple times.
I was able to remove the motor and found the shaft from the motor was rusty and binding in the housing.
I was able to disassemble the motor and clean the rust off the shaft,greased with synthetic grease and its been good for the last 7 years.

I like your solution!

I was in the barber shop yesterday getting a haircut, and listened to the barber and client sitting in the chair discuss door hinge lubes for his late model GM pickup. He had been using a graphite lube for quite some time, but the squeak always came back in a short time. This last time, in a moment of desperation while away from home, he sprayed the hinge pins using spray sun blocker... He said it's been a while since then, and the squeak hasn't returned... Jim
