I'm having trouble with my windows. I replaced the driver side motor to find that it still didnt work. Hooked up the old one to find that it works in the up position, but doesnt work in the down postion and will not control the passenger side at all. I thought it was the switch so I got one from a salvage yard. Plugged it in, same result. Bought a new switch today but havent tried it yet. If that doesnt fix it, any suggestions
