Turn the ventilator glass to the closed position and adjust the glass and frame up or down as necessary to provide the proper clearance for the bottom of the frame on the rubber weatherstrip. Install and tighten the ventilator shaft to regulator bolt, Fig. 18. 4. Properly line up the door division channel, then install the screws attaching it at the top and bottom of the door opening. 5. Reassemble the door trim pad, all handles, and the door window garnish molding. Ventilator Adjustments Should a front door ventilator glass and frame move too freely or develop excessive play or travel in relation to regulator handle movement, correction may be made as follows. Remove the door window garnish molding, loosen the door trim pad at the top and down both sides about twelve inches to expose the ventilator regulator. Tighten the ventilator shaft to regulator bolt (top bolt in Fig. 18) which will reduce such excessive play or movement.


	Fig. 17-Ventilator Attaching Screws to Door Opening 4. Remove the bolt attaching the ventilator shaft to the regulator body, Fig. 18. Turn the ventilator glass to about one-third open, then, while carefully releasing the rubber weatherstrip, lift the ventilator assembly out of the opening in the door. Installation 1. Clean all old rubber cement from the ventilator opening in the door and from the sealing surface of the weatherstrip. 2. Coat the edge of the door panel and the ventilator rubber weatherstrip with FS-655 rubber cement. Install the ventilator assembly in the door opening, making sure that the lip of the rubber weatherstrip is properly positioned over the edge of the window reveal. Install the ventilator attaching screws to the window opening.
		Fig. 18-Ventilator Shaft Bolt and Friction Adjusting Screw A ventilator regulator which operates too freely or too hard, resulting in failure to remain fully closed unless locked in case of the former, may be corrected by tightening or loosening the friction clamp screw on the regulator mechanism, lower screw shown in Fig. 18. This adjustment point is reached by the same disassembly procedure outlined for the foregoing adjustment. Excessive play at the ventilator glass frame upper pivot, which may develop after long service, may be corrected by spreading apart the lower end of this pivot which is slotted. Ventilator Safety Locks The sliding bolt type ventilator safety lock is riveted to the ventilator glass frame, Fig. 19, and serves to prevent breaking into the car when locked by prying the ventilator glass open.
