I just bought a 90 5.0 convertable from my grandfather. I've had the car for two weeks and already theres problems. My right rear window doesn't go down or up. When i push the button i can hear a clicking noise like the actuator is trying to push it up. Is this a bad power window motor? Also when i start it up its hesitant to move, its kind of jerky. Is this a fuel pump problem? I NEED HELP. Any advicewould be appreciated.thanks and gig'em
