SYMPTOM/CONDITION

Inadequate sealing of the blend air door on subject model vehicles built prior to October 1, 1985, may result in customer complaints of poor A/C performance, and/or warm air coming out of the floor outlets in the bi-level mode when the temperature lever is in the full "Full Cool" position.

DIAGNOSIS

1. Position A/C controls as indicated below:

a. Panel mode.
b. Blower on medium speed (M2).
c. A/C switch is on.
d. Temperature lever in recirc.
e. Close off all panel outlets except left center.

2. Idle engine with hood closed for ten minutes and record temperature coming out of left center outlet.

3. Move temperature lever to "Full Cool" position and record temperature at left center outlet after five minutes at new setting.

4. If difference between temperatures recorded above is more than 8~ F it is possible that the blend air door may not be sealing.
