I have a 1996 GMC Savana conversion van by Autoform (Glaval). I
purchase this van two years ago used from a Ford dealer.
Recently, the door won't lock when the alarm is activated. The key-fob
says Auto-Mate on it with DEI on the back.
The van has power locks that function normally when operated manually.
When I press the arm button on the key-fob the parking lights blink,
there is a "boop", the alarm activates, but the doors do not lock.
I activated the alram while inside the van and the lights on the door
lock buttons illuminate when I activate the alram, and again when I
deactivate the alarm. I also hear a "tick" (tick tick) like a relay is
clicking when I activate the alram (sounds like under the dash) and
two ticks (tick tick - tick tick) when I deactivate the alarm.
The Ford dealer won't touch this because they say it is aftermarket
and not a factory repair. They say the power locks are operating
normally. They sent it out to a GMC dealer and they said the same
My guess is I lost a fuse or a wire somewhere. Anybody know where I
can look or find a wiring diagram?
