Yes. It can be done.

Thanks Meir. Can't find any info on window switch as far as which contacts. Just need power and ground as I do not want to have illuminated.

[Meir]

To use the window switch as a garage opener you do not need power or ground if you do not want it aluminated.
You just need to solder 2 wires to the garage remote button contacts, and then connect them to the window switch.
By pressing the switch yo are closing a dry contact.
Let me see if I have one around, and I will post a pic.

Leg #4 is your common.
so whatever you are going to connect to it, will close a circuit with leg # 1 when pressing one side of the switch, and with leg # 2 when pressing the other side.
if you connect both legs together as shown, the garage door will open no matter which side of the switch you press.
this is all assuming you have the type of remote that has the same button for closing and opening.
if you have 2 buttons, well.... i'll have to make another drawing

This is perfect Meir, thanks. Yes the opener just has one button open and close. So the #1 & 2 terminal could be used for the left and right door so I would solder to the contact buttons on the opener? #4 would be soldered to what on the opener board?

you will have to identify the pins on the board that operates the garage door.usually there are 4, but you will need to use only 2.
what i usually do, is take a paper clip, open it, and use it to create a shortcut between the button contacts.
once you identify which two contacts open the door, it doesn't really matter which one will be connected to the leg #4 and the switch, and which will go to the #1&2.
if you post a pic of the remote i might be able to help more.
if its a liftmaster i might have one.

I did this hack right after I bought the car. Works like a champ.

Thanks Meir, I will get pics of remote today.

Great, did you use the Targa switch or some other type switch?

i personally used the targa switch, just for the icon.
the switch itself is the same as your window switch. after all, the targa is just a large window.

Here you go

[Meir]

Ok.
You have three buttons on the remote. Which one opens the garage door, and what the other 2 are doing (if at all)?

[redciv1]

The remote can control 3 doors. Button with 3 lines is not used.
Buttons with 1 and 2 lines are used for 2 dr garage.

[Meir]

got it.
before we start doing anything, we need to confirm and locate the correct contacts.
since this remote does not have the classic PCB mount push button (this one is called carbon contact silicon), it's going to be pretty easy to test.
grab a small flat screw driver and step outside with the remote disassembled in your hand.
lay the screwdriver in a way that it connects the two lines that i marked in red.
start with #1 then go to 1a and so on until you tested all 6 contacts.
if i got my orientation right, then 1 and 1a will open and close one door, 2 and 2a will open close the other door, and 3 will do nothing.
once you confirm that, we can move to the next step.

[redciv1]

Exactly right sir. 3a and 3 are not assigned.

[Meir]

this is the configuration you will need, to open 1 door, by pressing the switch to any side.



if you want to open 2 doors, you will have to figure out which one of the contacts is the common. you will need a voltmeter to test it, or solder the wires and experimenting by touching the other contacts.
im almost positive that the one connected to the blue one is the common, but it's always good to test first.

[Meir]

assuming the blue is confirmed as the common, here is a configuration for 2 doors.



when you are soldering the wires, remove the battery from the remote.
