Insert key in ignition.  Open door.  Get your ear up close to relay
panel.  Determine by touch and/or sound which relay is making all that
annoying racket.  Remove key.  Disconnect battery ground in you are
really anal (I am).  Pull out the noisemaking relay.  Reconnect battery.
Bag and label the relay in case you ever want to put it back in.

Insert key.  Open door.  Ahhhhhhhhhhhhhhhhhhhhh!  Blessed silence!

I have done this to all the vans I have owned.  Easy, quick, silence is
golden!

Best wishes,
