CONDITION:

SOME OWNERS MAY COMMENT ON INSUFFICIENT HEATER PERFORMANCE ON THE PASSENGER SIDE FLOOR AREA.

CAUSE:

THE RIGHT SIDE HEATER OUTLET MAY BE PARTIALLY COVERED BY THE INSTRUMENT PANEL INSULATOR PANEL (HUSH PANEL). THIS CONDITION MAY BE ATTRIBUTED TO A WIRING HARNESS BEING SLIGHTLY OUT OF POSITION AND NOT ALLOWING THE INSULATOR PANEL TO BE INSTALLED PROPERLY.

IMPORTANT:

VEHICLES THAT ARE NOT EXPERIENCING THIS CONDITION AND NEED REPLACEMENT OF THE INSULATOR PANEL MUST INSTALL THE FOLLOWING ITEMS. THE OLD STYLE PANEL WILL NO LONGER BE AVAILABLE FROM SPO SO THE VEHICLE MUST BE UPDATED TO THE NEW STYLE PANEL AND BRACKET.
