hello, I installed an RF-520LCD from autopage in a 2000 vw jetta. As you guys know, if you extend the ground to the lock wire it will roll the windows up and close the sunroof, wich i did, everything was working just perfec for a few days, but now the alarm does not lock or unlock the doors, plus the windows won't roll up using the car key anymore, please help. thank you

Did you check the fuses in the car?

Check the fuses for the door locks first, but since they are controlled by the computer in the driver's door, it may not help you too much. Do they still work with the factory remote? Pull your door panel apart and check your connections. You may have broken a wire, or have a grounding problem in the door itself. Also, disconnect your door lock wiring. The autopage may have gone bad, and is pulling down the factory lock/unlock wires enough that they won't trigger the door computer anymore. I usually use diodes on my lock wires on VW's just in case.
A few things to try.

First of all, thank you guys foy your time. yes, i tested all my fuses, I forgot to tell you that the factory alarm still works with the vw remote, and the doors lock and unlock work normally using the vw remote and from the switch in the car, but not with the autopage remote, i also tested the lock/unlock output wires from the alarm, they seem to be fine , I soldered all my wires, so i don't know, the only programming i did was extended the ground pulse to lock the doors up to 10sec... thank you again

try adding relays to the aftermarket alarm it may not be a strong enough output for the car to trigger the door locks

And they still work from the key switch in the exterior of the door, correct? If not.... disconnect the aftermarket wires. Now? If so... add a pair of relays. The brain is loading down the factory stuff somehow. The relays will isolate the alarm from the car, and provide a definate, strong ground pulse.
