REPAIR PROCEDURE:
This bulletin involves accessing the lower pivot and contact surfaces of the blend air door shaft to apply rust penetrant to free up the shaft and then apply lubricant to prevent further corrosion.
1. Remove the center floor console on vehicles so equipped.
2. Remove the floor air distribution duct.
3. On the extension which houses the blend air door shaft inside the heater-A/C housing (Refer to Illustration), drill a 3/32 in. (2.2 mm) hole perpendicular to the side of the extension and 3/8 in. (10 mm) up from the bottom of the extension to gain access to the blend air door shaft.
4. Spray a sufficient amount of Mopar Rust Penetrant into the hole drilled in step 3 and work the temperature control lever until it moves freely.
5. When the door moves freely, inject Mopar White Spray Lube into the hole for two seconds time in order to prevent further binding/sticking in this area.
6. Wipe the housing exterior clean of any excess lubricant and tape over hole in extension with black duct tape.
7. Install floor air distribution duct.
8. Install center floor console if equipped.
9. If movement of the temperature control lever is still difficult, inspect the temperature control cable where it attaches to the control for kinks. If kinked replace the temperature control cable. Refer to the appropriate service manual for cable replacement procedure, and the appropriate Labor Operation Time Schedule Manual for cable replacement time allowance.
