Scheme 23

Remove the headliner (see «HEADLINER REMOVAL/INSTALLATION»(/acura/mdx/i-2000-2006/remont/exteriorinterior-trim/#interior-trim__headliner-removalinstallation) ).
Closing force check: With a shop towel (A) on the leading edge of the glass (B), attach a spring scale (C) (Scheme 22) Have an assistant hold the switch to close the glass while you measure the force required to stop it.

If the force in not within specification, remove the moonroof motor (see «MOTOR REPLACEMENT»(/acura/mdx/i-2000-2006/remont/sun-rooft-topconvertible-top/#moonroof) ), then check: The gear portion and the inner cable for breakage and damage. If the gear portion is broken, replace the motor. If the inner cable is damaged, remove the frame (see «FRAME AND DRAIN TUBE REPLACEMENT»(/acura/mdx/i-2000-2006/remont/sun-rooft-topconvertible-top/#moonroof) ), and replace the cable assembly (see «DRAIN CHANNEL SLIDER AND CABLE ASSEMBLY REPLACEMENT»(/acura/mdx/i-2000-2006/remont/sun-rooft-topconvertible-top/#moonroof) ).
