I'm guessing, but I don't think the heater relay is involved with the mechanized carriage. If you have 12vdc into the seat (you said you did right?), use your meter to track down where the break is. If the motors spin with direct voltage, there must be a break between the input and the motor.
Every time I've had this sort of problem, its been a switch. But you said the switches worked on the other seat. So maybe its a broken wire. One thing to note is the seat motors don't use a proper ground. That's because the polarity gets reversed by the switches.
