Blower Motor / AC Condenser Cover

1996-2005 vans the Blower Motor / AC Condenser Case is enclosed by a plastic cover. In the factory service manual it is referenced as an Acoustic Cover. In the parts catalog it is called an Insulator. With age these are prone to get brittle and easily crack and break apart.

Inlet side (covering the blower):ACDelco 52478147 Insulator

Outlet side: ACDelco 52471300 Insulator

Most important is the case under the brittle cover, should this break it will allow air from the engine bay into the HVAC system.
