screwdriver to help me remove the little plastic wiring harness tie downs from their mounting positions. The tie downs clip into holes in the sheet metal. The last step before tray removal is to detach the drain tubes from each corner of the tray. The tubes are held in place by simple metal clamps that can be easily removed by hand. Slide the clamps down the tubes and then remove the tubes from the tray nipples. This may take a bit of twisting on the tubes to get them loose. BTW, I tossed the factory clamps and replaced them with sturdier worm drive band clamps. Inspect the tubes and use compressed air to clean them out. DO NOT remove the tubes from the chassis unless absolutely necessary. They don’t just slide back in with ease. The rear tubes extend alongside the hatch (through the unibody cavity) and actually empty onto the ground at the rear corners of the car. The sunroof tray is attached to the roof via two bolts at the front, two at the rear and two on each side (10mm hex). Remove the side bolts first, followed by the rear bolts. Leave the front bolts in until you are ready to drop the tray. Note that the rear of the tray is suspended by hooks that keep it from falling on your head. Honda does things right. Now hold up the front of the tray with one hand while removing the front bolts with the other. The tray will now come out easily. Be careful not to rip the interior with the sharp corners of the tray assembly.

I found it best to slide the seats as far back as possible and tilt the seat back to about a 45 degree angle. This allows you to lay in the seat and drop the sunroof tray right into your lap.

SERVICING THE TRAY

REAR LIFT MECHANISM

Once the tray is out of the car, now is a good time to get all of your cleaning supplies together. I used 3M General Adhesive Cleaner (works great on oil and grease, too), WD40 and a bath of water and Castrol Super Clean to soak some really nasty stuff. My CRX had been spray painted at some point so there was lots of overspray in the sunroof mechanism. I decided that it would be best for me to just take the whole thing apart. That way, I was able to inspect most of the moving parts, clean them up and then re-lubricate in the necessary spots. I did leave the motor alone as it was working fine.

You MUST have the roof mechanism in the CLOSED POSITION in order to disassemble the tray assembly. If you haven’t already done this, STOP NOW. Hook the tray back up to the sunroof motor wiring harness and close the mechanism using the sunroof switch. This will allow access to all the necessary fasteners during assembly.

Most steps below must be carried out on the left and right sides of the tray assembly. Refer to the Tray Assembly Photo. Each number below is reference in the photo so that parts can be more easily identified.

  • 1)

    The wind deflector must be removed. This only requires one bolt per side (Philips head) and then it will just lift right out. My deflector was working fine and undamaged besides the weathered rubber strip.

  • 2)

    Remove the plastic covers that cover the threaded shaft “loopback”. They are attached with one Philips fastener per side and are located on the inside near the roof opening. The “loopback” is where the excess length of the threaded shaft goes to when the roof is opened.
