I know how the Hatch motor functions, but in the schematic I have the console hatch release switch is not shown. It seems like the hatch motor requires a physical switch (key or striker) to be moved in order for the hatch to be pulled up or down. Does anyone know how the console switch operates the motor?

Thanks, Doug

 

The console switch does not control the hatch motor, it controls the actuator that releases the hatch. The switch and the controller for the motor are located in the latch mechanism itself.

press the switch in (the one in the latch mechanism) and the motor goes down (if you release the switch before the motor is all the way down, it will stop.)

The motor will stop automatically when it reaches the bottom, when the switch is released, the motor will go up. (pressing the switch befor the motor is all the way up will make it go down again, releasing it will make the motor stop, press the switch again to make it go down untill it reaches the bottom)

Some people mistake it for a 'reset' switch because when they press it, the motor goes down and comes back up when they let it go. keep in mind that the motor has to go all the way down before it can go up. If you stop it on the way up, it has to go all the way down again.

 

even though you have the release switch on the center console does not necessarily mean that the hatch release actuator is installed in the car.

thirdgens are older cars. parts wear out and get replaced with salvage yards ones from other cars. your car may not have the original console or hatch pulldown setup still in it.

 

Thanks, guys.

I'm not looking to repair my switch (mine works fine), but design something that will open the hatch as an alternate to the console switch. I am designing fingerprint activated entry for my car and need an idea of the circuitry involved.

Thanks for your help,

Yep just apply current for 2 sec to the wire that goes to the back from that center console switch from your security system and the hatch will open.

 

Does the power door lock switch just apply 12V to either side of the lock actuator, causing a move in one direction or the other?

Thanks,
Doug

 

I think so, check the manual on the wiring digram.

 

hmmm, fingerprint activated devices + car exposed to rain & snow do not mix well.

might take a look at http://www.taplock.com if you're looking for a keyless entry system that doesn't need remote fobs.

Actually.... the sensor is built to operate in extreme outdoor conditions. As for the snow, I'm installing a heater to keep the sensor at 40 degrees or so. That, and its only a project - it won't actually go on my car.

Thanks for the schematic.

another good idea - shaved door handles with remote keyless entry (the remote pops the doors open)

 

in many states a car with shaved door handles will not pass the annual safety inspection.

 

are you serious? how would that be a violation?
