This Bulletin contains revised Warranty information. Please discard NTB94-019 dated February 17, 1994.
APPLIED VEHICLE: All models equipped with power antennas
Power antenna incidents for no operation or improper retraction are almost always caused by the following:
The antenna rod is broken or bent due to misuse. Common examples of this include the antenna contacts the top of a garage door opening or a tree
branch. Also, a customer may forget to lower the antenna before entering an automated car wash.
Dirt, road grime, and other foreign matter collects on the rod interrupting proper operational movement. This occurs most frequently during winter
months in areas where road salt and other chemicals are splashed onto the antenna rod.
REPAIRS COMPLETED FOR THE TWO CAUSES DESCRIBED ABOVE ARE NOT COVERED UNDER WARRANTY. ONLY REPAIRS
UNDERTAKEN DUE TO DEFECTS IN MATERIAL OR WORKMANSHIP WILL BE COVERED UNDER WARRANTY.
In a large majority of cases, the antenna motor is fully operational and receiving proper power. Therefore, replacement of the entire power antenna
assembly is not usually necessary to restore power antenna operation. Prior to removing any power antenna assembly, an attempt should be made to
repair the power antenna by removing dirt, road grime, and other foreign matter, and then lubricating the antenna rod sections as appropriate. if still
inoperative, replacement of the rod only should be made. A sample replacement procedure is provided on the following page. Check the EL section
under Audio and Power Antenna in the Service Manual for specifics on your respective vehicle.
REPLACING THE ANTENNA ROD
Remove antenna nut and base. (Figure 1)
Turn the radio to "ON" and the antenna rod will extend*. Assist the antenna rod to fully separate from the antenna base. Note the direction of the
gear section on the antenna rope. [The new antenna rod must be installed in the same direction].
If the antenna rod does not extend, always check the power supply to the power antenna before replacing the power antenna assembly.
