I have a 2003 mitsubishi eclipse spyder. I just did all new interior and a new converitble top. Every thing was work in all for windows and the top. I have started it in a few day and now my back windows or my top will not go down but my front window work. I have checked all the fuses and the motor don't even make a noise when the switch it pressed. Where do check next?

Here are the procedures for diagnostics and repairs.

INSPECTION PROCEDURE 3: The Electric Convertible Top does not Open or Close at the Vehicle Speed of Less than 3 km/h (1.9 mph). (The Door Windows and the Quarter Windows do not Automatically Lower when the Convertible Top Switch is Operated. Also, the Quarter Windows do not Operate when the Power Window Main Switch is Operated.)

CIRCUIT OPERATION
When the convertible top switch is operated, a signal is sent to the convertible top control module. The convertible top control module sends convertible top switch "ON" signal to the power window main switch to lower the door windows automatically. The power window main switch lowers the door windows and simultaneously sends the "AUTO DOWN" signal to the convertible top control module. When the "AUTO DOWN" signal is received, the convertible top control module drives the quarter window regulator motor to lower the quarter windows and simultaneously drives the topstack drive motor assembly to operate the electric convertible top.

TECHNICAL DESCRIPTION (COMMENT)
The cause may be a malfunction of the topstack control module circuit.
