welcome to the site, and i would check all the wires leading to the motor/switch before you buy the new motor, but to be honest i think it would be a better idea to just replace the motor now. also...try replacing the fuse. i know it sounds like a weird idea, but the same thing happed to my power seat. for awhile it had acted a little funny and it wouldnt go up or down, just front to back. afew hours later it would work fine, then a few days later it would be back to the same thing. finally one day it just went out on me all together, checked all the fuses and everything was fine. months later when i go to finally get it replaced, the new (used off of ebay) seat track doesnt work either...i check the fuses again and sure enough one is burned out. replaced it and now both seat tracks work perfectly. and yes, i checked the fuses, i had my fried check them, and i had his dad (mechanic) check the fuses and switches and everything and we concluded it was the seat track because we never found a blown fuse.
