This TSB article is being republished in its entirety to update the model year application and to revise the part number specified.

ISSUE:
The factory-installed power moon roof may exhibit "windnoise/buffeting" at speeds between 35 and 45 MPH (56 and 72 KM/H) when fully open. This occurs because the wind is unable to clear the opening without coming into the passenger compartment.

ACTION:
Take one of the following actions to resolve the concern.

1. Advise the customer to close the panel from the full open to about 2/3 open when traveling at speeds between 35 and 45 MPH (56 and 72 KM/H). This causes the wind to clear the smaller opening without coming into the passenger compartment.

2. If Step 1 is not acceptable, change the power moon roof motor to the 1994 design level (F4LY-15790-A). This part has an automatic stop at the desired low speed position as well as the full open position. Refer to the 1993 Thunderbird/Cougar or Mark VIII Service Manual, Section 01-17, for service details.
