SYMPTOM CHART

Glass Height Adjustment

The roof panel (A) should be even with the glass weatherstrip (B), to within 2 +0.5/-1 mm (0.08 +0.02/-0.04 in.) all the way around. If not, make the following adjustment

Scheme 2

Scheme 2: Glass Height Adjustment

Scheme 3

Tilt-up the glass.
Loosen the bolts on each side, and adjust the glass (A).
If necessary, repeat on opposite side.
The side-to-side fit of the glass weatherstrip can be adjusted by loosening the frame mounting bolts and moving the frame right or left and forward or backward by hand (see «FRAME AND DRAIN TUBE REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) ).

With an assistant holding the frame (F), remove the bolts (G), starting at the rear. Release the rear hooks (H) by moving the frame forward, then remove the frame.
With the help of an assistant, carefully remove the frame through the door opening. Take care not to scratch the interior trim and body, or tear the seat covers.
To remove the front drain valve (A) from the body, remove the kick panel, left or right (see «TRIM REMOVAL/INSTALLATION - DOOR AREAS»(/acura/rsx/i-2001-2004/remont/exteriorinterior-trim/#interior-trim__trim-removalinstallation-door-areas) ). Detach the clips (B, C), and on the left A-pillar, release the interior harness (D) from the clips (C).
To remove the rear drain valve (A) from the cargo area, remove the cargo area side trim panel, left or right (see «TRIM REMOVAL/INSTALLATION - CARGO AREA»(/acura/rsx/i-2001-2004/remont/exteriorinterior-trim/#interior-trim__trim-removalinstallation-cargo-area) ). Release the rear drain tube (B) from the clip (C), and tie a string to the end of the drain tube, then pull the drain tube down out of the C-pillar.
Install the frame and drain tube in the reverse order of removal, and note these items: Before installing the frame, clear the drain tubes and drain valves using compressed air. Check the frame seal. Clean the surface of the frame. When installing the frame, first attach the rear hooks into the body holes. Make sure the connector is plugged in properly. When connecting the drain tube, slide it over the frame nozzle at least 10 mm (0.39 in.). Install the tube clip (A) on the drain tube (B) as shown.
Check for water leaks. Use free-flowing water from a hose without a nozzle. Do not use high-pressure water.

Remove the frame (see «FRAME AND DRAIN TUBE REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) ).
Remove these items from the frame: Sunshade (see «SUNSHADE REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) ) Motor (see «MOTOR REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) )
Remove the screws, then remove the drain channel (A). Take care not to twist or lift the drain channel seal (B).
From both sides, remove the clips (A), nuts (B), and screws (C), then remove the front drain channels (D) and front rail holders (E).
Put on gloves to protect your hands. From the motor bracket portion and both guide rail portions, remove the screws (A, B) and nuts (C), then remove the guide rails (D), grommets (E), and cable assembly (F) from the frame (G). Take care not to bend the cable tubes (H).
From both sides, remove the anchor springs (A) and glass bracket (B), and slide cable assembly (C) rearward.

Scheme 25

Remove the headliner (see «HEADLINER REMOVAL/INSTALLATION»(/acura/rsx/i-2001-2004/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) as shown. Have an assistant hold the switch to close the glass while you measure the force required to stop it. Read the force as soon as the glass stops moving, then immediately release the switch and spring scale. Closing Force: 200-290 N (20-30 kgf, 44-66 lbf)
If the force is not within specification, remove the moonroof motor (see «MOTOR REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) ), then check these items: The gear position 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/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof) ), and replace the cable assembly (see «CABLE ASSEMBLY REPLACEMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof__cable-assembly-replacement) ).

Go to step 4.
Opening drag check: Protect the leading edge of the glass with a shop towel (A). Measure the effort required to open the glass using a spring scale (B) as shown.
If the load is over 40 N (4 kgf, 9 lbf), check these items: The side clearance and glass height adjustment (see «GLASS HEIGHT ADJUSTMENT»(/acura/rsx/i-2001-2004/remont/sun-rooft-topconvertible-top/#moonroof__glass-height-adjustment) ). For broken or damaged sliding parts. If any sliding parts are damaged, replace them.
