Rear Blower Motor

The rear blower motor is one of the '65 Sting Ray's hidden secrets. Located behind a carpeted panel on the left side of the cabin, the blower was first introduced on the '64 model. Connected by a duct to the b-pillar vent on the driver's side of the car, it was intended to remove hot air from the otherwise unventilated rear compartment, however it proved to be ineffective and was discontinued after the '65 model.

The blower has 3 speeds, with the speed control switch connected to a knob under the dash via a cable that runs along much the same path as the radio antenna cable. The knob looks just like the vent control knobs, so for years I thought it controlled the b-pillar vent, I wasn't aware that the blower had a speed control.

The speed control cable on the Red Rocket is broken, so I decided to remove the carpeted panel to take a look at what was going on inside.

The cardboard backing on the carpeted panel was in very poor condition, a previous repair had failed and the backing was now broken in the middle. I made a new backing board using 3mm PVC foam board, reusing the original metal eyelets to reinforce the mounting holes. I carefully glued the carpet to the new board using 3M High Tack spray adhesive. The original wire mesh screen at the rear of the blower motor cover was missing, so I made a new one using zinc-coated wire mesh.

Top to Bottom: 1: New backing board made from 3mm PVC foam board. 2: New wire mesh screen covering rear of the blower motor. Note the 3-position switch and cable, this will have to be replaced with the correct cable. 3: Finished restoration with screen and carpeted cover in place.
