6. Disengage the cable from the retainer at the top of the heater plenum, and remove cable from vehicle for testing or replacement. NOTE: It will be necessary to remove the glove compartment to gain access to the antenna lead-in cable.

Installation
1. Insert the antenna lead-in cable from the passenger compartment into the antenna hole in the cowl.
2. From outside of the vehicle, pull the cable through the hole in the cowl until the grommet on the cable is properly seated.

Poor Reception
- If AM reception is extremely poor and FM reception "spits" or appears to have trouble holding stations, make sure the antenna and antenna connectors are properly mated. If the antenna connectors are properly mated but the reception is still poor, refer to Antenna Tests 1 through 3.
- If only FM reception is poor, it is unlikely that the antenna is at fault. Remove the radio chassis for service.

NOTE: Many customers do not understand the limitations of FM reception. Refer the customer to the Owner Guide for information about the limitations of FM radio performance.
