Chevrolet Astro

I have a 1999 chev astro with 192,000 miles and a 4.6 lieter engine. The driver side power window will go down about 3\4 but will only raise up in small increments. Note: I recently replaced the motor with one I purchased from a auto salvage yard, and this does work better than the previouse motor. Is there a posibility the switch is bad or did I just get a weak motor. Also neither power mirror works.

There is a rubber boot between the van and door, slice it open and look for broken wires. Try the driver side first, and good luck
