Battery failed and lights flashing?
Parking lights will flash when the vehicle's battery is disconnected and reconnected.

Press remote transmitter "UNLOCK" button once OR turn the ignition switch to the "ON" position and press programming button for one second (see below).
The vehicle interior (courtesy) light and door open warning light (DOOR AJAR indicator) will then illuminate for 60 seconds when the ignition is turned off, or until the doors are locked with the remote transmitter. Yes, the dashboard instrument panel lights will flash when the parking lights flash.

Programming or Overriding the Alarm when you have lost the remote

Code Alarm Programming Button is under dashboard on the kick panel by the driver's left knee, left of the steering column. If you can't find it, it might still be tucked up in the wiring harness higher up in that same general area. The botton is recessed in a plastic ring (see diagram).
This button must be pressed while programming remotes or if the battery was disconnected and the lights are flashing.

If the power window itself still work fine, and the illumination on the driver's side door lock still work, then the LEDs behind the switch are the issue ( usually bad solder joints ).
If you are talking about all doors other than the driver's side, do you have the window lock on ? The lights on the switch turn off when the driver's side window lock is enabled.

THE PROBLEM SOUNDS LIKE LOOSE WIRING CONECTIONS IN THE DRIVERS DOOR , BEST THING TO DO IS HAVE A LOOK OPEN UP DOOR PANEL AND CHECK ALL CONECTIONS, GOOD LUCK

couls be an old alarm in the van from previous owners and it keeps setting off and then flashing noise woud come from that unit

Sounds like the relay

It's on the driver's side about half way up the dash. Almost ,kinda sorta by the back of the headlight switch. They're a pain in the ***. If I remember right I used to take the head light switch out to get it.

Its under the hood drivers side on the upper firewall.

check innegration relay made to fuse block under dash driverside
