  Q: How to service and repair the convertible top motor on Ford Mustang?

  A:

  Unlatching the convertible top and removing the rear quarter trim panel, rear seat cushion pad and frame, and rear seat backrest pad and frame are the first steps to servicing and repairing the convertible top motor. Unplug the electric connectors and remove the screws, speakers, two cylinder rod mounting bolts and lower the lift cylinders completely. Remove nuts and lift cylinders, loosen hydraulic line retainers on each side and disconnect motor electrical connector. Pull up on the motor to release the rubber retainers and remove the motor and cylinders as an assembly, ensuring to mark the hydraulic lines for correct installation. To install, use thread locker to attach the hydraulic lines to the lift cylinder and make sure that each fitting is in the proper position; then install the tetra seal in the bottom of each hydraulic cylinder port prior to attaching the hose fittings. Repeat this process for the motor assembly. Remove the fill plug from the hydraulic pump and pour Mercon(R) Multi-Purpose Automatic Transmission Fluid XT-2-QDX or equivalent into to the bottom of the fill hole and put the fill plug back in. With the motor connector connected to a 12 volt source, run the motor until the cylinders are fully extended, then reverse the connection and completely retract the cylinders, repeat three times. Inspect fluid level, refill as needed and replace fluid fill plug. Then, assemble and install the motor and cylinders, install the motor assembly, and attach the motor electrical connector. Install hydraulic line retainers, set lift cylinders and install nuts and two cylinder rod mounting bolts. Reinstall speakers and screws, reassemble electrical connectors (vehicles with the Mach sound system only), and then reinstall the rear seat backrest pad and frame, rear seat cushion pad and frame and rear quarter trim panel and latch the convertible top.

  Q: How to service and repair the convertible top motor on Ford Thunderbird?

  A:

  Servicing a convertible-top motor typically begins with the hydraulic assembly being removed as a unit and the system being bled before it is reinstalled; with the top closed and unlatched, the interior well-sling trim cover is detached and the rear-window defrost-grid electrical-connector locator is released from the body while the connector itself is left attached to the glass in some cases, and the defrost grid lead is routed through the hole in the trim cover after the ground bolt is removed and the ground wire is led out through the same opening. The two lift cylinders are set aside after their bolts and nuts are removed, the motor noise-reduction shroud is taken off, the motor electrical connector is detached, hydraulic-line retainers on each side are released, and the motor assembly is lifted to disengage rubber retainers so the motor and lift cylinders can be removed together as an assembly. Hydraulic lines are then disconnected from the lift cylinder and from the motor, with upper and lower lines being marked for correct reinstallation; during refitting thread locker is typically applied to the hydraulic fittings, each fitting is positioned correctly and a tetra seal is placed in the bottom of each port before hose attachment, and the same procedure is followed for the motor. The motor fill plug is removed and the pump is filled to the bottom of the fill hole with Mercon Multi-Purpose automatic transmission fluid XT-2-QDX or an equivalent, the plug is replaced, and a 12-volt source is applied to the motor connector to extend and then reverse to retract the lift cylinders-repeated about three times to purge air from the system-after which fluid level is checked and topped off if necessary and the fill plug reinstalled. Finally, the motor assembly and lift cylinders are installed and secured, hydraulic retainers engaged, the motor electrical connector and noise-reduction shroud are refitted, the lift cylinders are fastened with their nuts and bolts, the defrost-grid ground and signal wires are routed through the well-sling trim opening and reattached with their bolt and connector, the locator is reattached to the body, and the interior trim cover is put back in place.
