CRX sunroof electrical problem

Hi everybody!
Today I want to discuss one problem that I had for sometime - electrical switch problem in a sunroof circuit.

Sunroof switch location Problem: sunroof would open normally but wouldn't close. You'd have to play with the switch to close the sunroof.
Cure: Sand down and clean the contacts of the dashboard switch
 
Removing the switch. As my mechanic said it might be the cables problem in a sunroof mechanism, they might be old and need to be greased up.
I did take the whole sunroof unit out of the car and took it completely apart including the electrical motor. Well, motor was a bit burned inside and cables (there are four of them) didn't have enough grease.
I cleaned cables, greased them with Moly-Graph multi-purpose grease, cleaned the rest of the mechanism and put it all back together....
It didn't work!
 
Disconnecting switch. While I was taking switch apart I was taking pictures to make sure I can put together all the small parts. Then I thought I might be wrong here but mechanism works great! When it was out the sunroof would open and close under its own weight, so it moves freely.
I decided to look at the electrical switch that is mounted on the dashboard (picture above). To remove it you need to pull it with a thin screwdriver or a kitchen knife.
 
Switch removed. Now, when the switch is out you have to take it apart without breaking it.... You have to take it apart in two pieces. Inside you will find the actual contacts that got burned (sometimes real bad). The idea is to clean them and sand down the black stuff which prevents switch from working properly.
Get some sand paper, fold it a couple times and sand both contacts. The ones on the body of the switch and the ones on the leaves that is inside of the switch.
 
Switch taken apart. Once you finish with sanding and cleaning place leaves back inside, make sure they're in proper position (they are interchangeable so you do not have to worry about which one is which). Snap switch back together (you can't put it back the wrong way as it has a guide on one side).
 
Swith parts. You're done with the switch. Connect it back to the harness and insert in a dashboard.

Check the work of the sunroof, see if it closes just as fast as opens. If it does - you just saved yourself a couple bucks on a parts and labor!!

Sunroof won't open

The problem with my sunroof is the opposite. It doesn't open but it closes smoothly. I need to manually open it but it will close fine by using the switch. Does anyone have a suggestion? Thanks

Thanks, my crx body has 300,000 miles on it and the sunroof was working the same as yours until this year when the thing just stopped working. I replaced broken sliders and I tested the motor with a power supply to make sure its still good. Thanks to your post I have one less part to replace.

Great post my roof works like new now the switch is. A little difficult. To open but a pick and tiny flat head helped me and I had to clean even the outer round copper disc on each side I was about to dissemble the sunroof assembly. Glad I read this first thanks again

You are the greatest! I've had the same problem for sometime and made the mistake of opening the sunroof in my Si on this beautiful day and then it wouldn't close. With rain coming tonight I found your site and with your great pictures was able to fix it in a few minutes. Now I can enjoy great weather and stay dry when it rains. Thank you so much.
