From a whole file of Vanagon recalls by NHTSA that I downloaded from
vanagon.com web site files section IIRC:

-----------------------------------------
1986 Vanagon through
1991 Vanagon                Built from 1985 Aug  to  1991 Jun
Campaign 93V175000     No. Recalled: 29,500
Campaign SU            Notification Date:
System:                Air Conditioner hose; Duct; Air.
Vehicle Description:   Vans equipped with factory air conditioning.

Description of Defect: The plastic material of the center air flow duct,
which is fastened by two mounting  screws to the ceiling of the
passenger compartment, can crack and eventually break.

Consequence of Defect: If the plastic breaks where it is held at the two
mounting screws, the center air flow duct can separate from its supports
and cause injury to the passengers sitting in the center seat of the
vehicle.

Corrective Action:     Dealers will install a reinforcement plate at the
connections of both the center and
rear air flow ducts.

Hope this helps,

Sam
