How-To: One Touch Auto-opening Moonroof

[h2ooh]

Hey folks, I just figured out a way to make a "press-to-stop" function.

Where you would simply press "Close" to stop the moonroof from opening.
This is handy if you want to tweak the opening, or just crack it a little without opening it all the way.

All it takes is two-diodes, and a different order in the hook-up of the rest of the parts.
Fortunently, my parents bought at protege at the exact same time, so I will make a fresh guide using their car. (If they let me)

First of all I love the details of all your mods, you have some very interesting stuff. You mentioned in this post that you've modified the circuitry a bit to accomodate a stop option. I was wondering if you can provide some details in that so I can accomodate it into my design.

I'm currently trying to create a circuit so when you press the button it will open all the way, however if you continue to hold the button it will bypass this circuitry and function as normal. I also have the schematics for the P5 moonroof and will try to get the limit switches into play to bypass the tilt issues others have been experiencing. Not sure if that's been resolved but I haven't seen any post of it being fixed.

If/when I get things working I will be more and glad to share my design with everyone else.

For the guys with timing issues, your results may vary.
Going too long won't hurt anything, but it will prevent you from being able to close the moonroof until the capacitor reaches full charge.
You will hear a clicking if you try to close the moonroof right after it auto-opened. A drain resistor will help with this slightly, but is not needed if the right capacitor/resistor are used.
The values I used have worked perfectly for mine since I did the mod.

I actualy worked on trying to get the STOP function to work for hours.
The idea was to use the close switch to short-circuit the relay and kill the auto-open circuit. I can do this successfully, the problem is that if you continue to press close, the moonroof actualy finishes opening, due to the charge left in the capacitor. I will try another circuit this weekend.

As far as a "press to open" "Hold for normal operation" meaning you let the button go where you want it to stop, it is possible, but not with such simple circuitry.
You could use an timer (555 timer IC) circuit that can detect a "Short pulse" or missing pulse. Basicly it looks for a pulse that is not as long as it should be. (pressing the button a short bit)
If it detects a short pulse it activates the auto-open circuit.
If the pulse is longer (You are holding the buttton) then the timer ignores the pulse, and you moonroof works as normal.

i cant wait to do this mod!

hey zap! fix your website..cant see any pics, or even get to them on your website...

I applied this mod earlier this week and it worked great! I didn't use the drain circuit. Also, I used a 1.5kohm resistor as the 1.2kohm resistor I had was HUGE, I believe it was audio grade

One thing I was curious to is... why did you disconnect the battery when you can entirely remove the control console from the vehicle?

Anyways, great how-to and mod! A bump so others will see it and do it. Thanks!

I have thought about how I want to do the auto-window down.
What I now plan on is making it so that when I use the Auto circuit, both the driver's and passanger's window's role down.

That way I have normal control over both windows, but with the added auto-down function on both windows.

Have you completed this mod yet and if so how is it done? I would like to have this feature in my car. By the way the one touch sunroof is great!

All the pictures are broken on this how to at the beginning.

subbin. will probably be doin this mod once the spring comes and i actually use my sunroof haha
