The door locks on my van are a single wire and I cannot get the door locks to both work.  I can get it to either lock or unlock but that is all.  Any comments are appreciated.  Thank you for your interest and Happy Holidays.

There's an easier way. There are 3 relays on the front of the BCM, one for lock, one for unlock drivers, one for unlock the other doors. Pull the relays and tap a wire to pole 86, this will give you a straight negative pulse needed without the resistors even needed. It even gives you an easy way to get 2 stage unlock....

I had the similar problem before, using a 665 Ohm for unlocking and 4020 Ohm for locking, the factory default setting short pulse .9 ms from the BullDog Deluxe 500 Remote starter was only long enough to lock, but not long enough to trigger the unlocking, eventhough it was long enough to trigger an disarming signal successfully.

I reprogramed it to send a longer pulse 3.5 ms, then it unlockingall the doors.

If you have not attached any resistors to it, Mike M2 suggestion is the best way to go.
