Contour Enthusiasts Group Archives Forums Modifications General Mods sunroof control module

Ok, I can answer the last few posts in one reply.

It should not be a problem to roll up/down the windows at the same time as the moonroof, at least not for the module. It may take longer since the car is off and the voltage will drop lower, but that can be added in. It shouldn't even require any more than an extra transistor, so cost wouldn't be affected. My only concern on this part is safety. I haven't got express close on the factory switch due to accidents with hands, arms, heads, etc. If the windows are designed to auto-up, then there is the possibility that some idiot will have a child in the car...the remote will be triggered by accident...lawsuit....
I will think on that. express down of the windows is no problem.

As far as the range, yes it will suck like factory. Only thing I reccomend is to keep new batteries in the remote and to see if you hook up a separate wire antenna for the keyless entry. Right now the keyless entry is spliced inline of the factory antenna system and I think it doesn't work as well as a standard antenna wire like a car alarm. I may be able to look into that.
Thanks for the interest, and I will get back with the details on adding express down for windows, as well as debate the consequences of express up.
IF anyone has ideas on the SAFETY considerations of adding express-up for windows, please post your them!

I just thought about this. How would you beable to use it with a factory keyless entry. There are no avil. buttons left. And if it goes down automatically when you unlock the doors, the in the winter or rain whats going to happen?? I dont see how this would be possible with a factory system.

I am very interested in your system to auto open/close the sunroof and windows. Personally I find it really irritating (and distracting for that matter) to sit there and open/close the sunroof...and it sounds like a great idea to run it through the key fab. That is a good question though about the buttons on the fab. How will you get around this?

As for the safety concerns you have try this. Stick your hand in the window and roll it up. I know this doesn't sound very smart, but it's the only way that I can prove to you that it is not a safety conern. The window motors were designed to automatically shut off when they have a certain amount of 'backpressure' on them. However, I cannot speak for the sunroof because I have not 'tested' it, and really don't care to for that matter.

I guess what I'm saying in all this is that you should add as much content to your system as possible because that's what the customers (me and the rest of the people responding to you) want.

Hi, the problem to the button question is handled in the following manner:

i: open--Currently to open the sunroof (and windows if added) is 3 sequential presses of the unlock button on the factory remote. The module counts the pulses from the keyless entry system, and if it gets three in a certain time period then it rolls open the roof. This way one unlock opens the drivers door, two unlocks the passenger doors, and three rolls open the roof. You could add a 4th to roll down the windows, but that requires a change in the design I currently have.
2: close--To close the roof, you hit the unlock button once (it does nothing since the car is unlocked already, or unlocks it), then you hit the lock button. Pushing them in that sequence will roll the moonroof closed as well as locks the doors, and usually arms alarms if equipped. If the moonroof is closed already you just hit lock to lock everything.

So the answer is to use button combinations. I have decided that I will not add a window express-up feature due to safety. I will provide an auxilliary output to drive a relay or something like that if someone wants to hook up to it. That way when the close sequence is pressed, you can use it to turn on/off, open/close anything you want.

NOTE****I need all of the suggestions to come in the next week. I will get together with my partner and we will make any changes or modifications to the circuit design. We estimate that the module can be built and mailed to you for $55-$60, but you will have to buy your own relays. I'm using the same kind as the alarms use, the ones from bosch. I will include a full wiring schematic of the sunroof and how to wire the two relays into it. However, if you guys want the express down features on the windows, then I have to get hold of a schematic for it.

Okay, I get your point on features. That is why I have decided to add the auxilliary up/down or open/close outputs on the module. This way you can use them for whatever you want.
As far as the window's shutting off when something is stuck:

The motor on the windows and the moonroof have a circuit breaker on them. If the object (window/roof) are moving then the current flowing into the motor is lower and acceptable. If the object is stopped, the motor no longer turns and the current starts to peak towards a short in the motor because the resistance has dropped. This higher current spike is controlled by the circuit breaker. If the breaker is tripped, and you hold down the switch while still blocking the windows movement, then if will reactivate after the breaker cools down.
I use this circuit breaker feature of the motor into account with the timer of the module. I set the timer to run the relays just a little longer than the moonroof needs to close. When it reaches closed, the roof circuitry cuts it off. If that fails, then the breaker trips.

None of this is real important, suffice it to say that if you so choose to hook up something to the auxilliary outputs, then you can. Windows included. Just remember that when kids are concerned, that window is a lot stronger than it seems to you. I only make this point because I have two little children.

I'd definitely be interested in the one-touch and remote for the moonroof. The only use I can see for the express up is on the driver's window, but the one-touch and remote down would be handy on all four windows. Keep me posted.

Warmonger,

You still haven't sent me a wiring diagram yet. I thought you where giong to weks ago.

Thanks,

Sorry, I was trying to modify it to add on the items that people want. I will scan and send the older one tonight.

warmonger

Got the first one.
Thanks,
