97 Honda Civic Coup Power Sunroof

Is there anything else to check before changing the motors ? Yeah , hook up a factory or some other type of professional scanner an check for DTC'S - diagnostic trouble codes,also to see if the scanner will communicate with the modules. Changing batterys without a alternate power supply can cause modules to go to sleep permanently.

Power Sunroof System Components
The Power Sunroof and Sunshade System consists of the following components:
• Sunroof control module
• Sunshade control module
• Sunroof switch
• Sunshade switch
• Rail and track assembly upon which the sunroof and sunshade glass rides
• S/ROOF/SUNSHADE Fuse 30 A
• Body control module (BCM)


Don't be a parts changer, learn how to diagnose! So before you go wasting your money on parts not needed see if a professional scanner can communicate with all the modules on the vehicle.

The Power Sunroof System will operate only with the ignition turned to the RUN or Accessory positions, this allows for retained accessory power (RAP) control of the sunroof and sunshade through the body control module (BCM). With the ignition in the run or accessory positions, the BCM supplies the sunroof and sunshade control modules with ignition voltage which allows sunroof and sunshade operation. Once the ignition switch is turned to OFF the sunroof will continue to operate until any door is opened or when the RAP timer reaches its shut-off limit. For a description and operation of the RAP operation, refer to Retained Accessory Power (RAP) Description and Operation.


Circuit/System Description
The sunroof and sunroof shade modules supply each of the switch signal circuits with a 12-volt reference. When a switch is pressed the signal circuit is pulled low signaling the sunroof or sunroof shade open or close request. The modules determine the motor direction based on inputs received from the sunroof switches. When the modules reverse the polarity of the applied voltage, the motors reverse direction. The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. Ignition voltage is supplied to the sunroof and sunroof shade modules by the BCM. B+ is applied to the sunroof and sunroof shade modules via the S/ROOF fuse.
The sunroof shade module contains the logic for opening and closing the sunshade based on Serial Data from the sunroof control module. The sunroof shade module internally applies voltage and ground to the appropriate circuits of the reversible sunshade motor in order to move the sunshade panel to the open or closed positions.

check the fuses /relays then power feed to door and into switch cluster---sunroof off different feed ---damage wiring possible in harness feed between door hinge area --at cluster or failed door panel cluster but will need a multi-meter or at least a test light

Check the sunroof motor track see if there is an instruction or maby something is off track

There is a gasket seal that you can purchase to replace the seal. There really aren't any flaws I have heard of with the slide back power sunroof. (I am guessing this is the sun roof you have). There could be something caught in the seal. Check and see if you have a stick, acorn, or ect stuck in the seal first. The only other thing I can think of would be the final stage of closure on that particular sunroof not working. They close and then seat. Check the track ways to ensure they are not bent or jammed with something. Hope that helps.

it stands a chance the moror has broke its shaft or has slipped off the rails

It may not be clogged. I believe the sunroof drains run down
the roof pillars and then connect to another hose which exits
through the body behind front fender. Unfortunately the hoses
connect inside the car. Then again this might not be the source
of your leak and water leaks are hard to address. Your dealer
might be your best bet. If the sunroof drains are clogged, Honda
knows entry and exit and they have to be unclogged with compressed
air.

I have a 1997 Toyota Camry. Water was collecting on the front PASSENGER floor after a rain. I opened my sunroof and found the front drainage holes (about 1/8" diameter) in the corners of the track sunroof track. They looked clear. I poured a bottle of water in track and watched the result. Sure enough, water started dripping from the right ride of the glove box on to the floor. I started tearing out the interior panels to trace the leak. What I found is that if I poured the bottle of water REALLY slow into the sunroof hole = no leaks. But if I pour it too fast the small 1/8" hole cannot keep up and the track overflows! THAT is where the leak comes from in my car! If water overflows the track, then it makes its way down the column trim, around the glove box and on to the floor.

So I need to help the 1/8" sunroof hole drain faster. I took some 18AWG TFFN electrical wire and jammed it into the hole to help clean it out. I then removed the black plastic mud flap behind my front tire and blew out all of the leaves and rotted debris that where behind that flap. It was packed with junk! I poured more into the 1/8" hole and it seemed to drain quicker.

I hope this information helps others.

check fuses.

The side steel mechanism maybe jammed or worn, or possible foreign object jammed within the mechanism. Ii will require taking the sunroof apart, unless you can free it. Possible sunroof mechanism replacement. Hopefully this helps

You need to open the sunroof fully and locate the small drain holes at each corner. They will be blocked with debris. Get a piece of welding wire or the likes and carefully unblock the hose by prodding and pouring water down it. When cleared the water shout run away freely.
