WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Always zero out the DMM before taking a resistance measurement in order to ensure an accurate reading.
  1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure (Single Battery)Battery Negative Cable Disconnect/Connect Procedure (Auxiliary Battery) in Engine Electrical.
  2. Disconnect the antenna lead-in connector from the radio receiver.
  3. Measure the resistance from the negative battery cable to the coax outer conductor connector.
  4. The resistance measured should be 0.20 Ξ© or less.
  5. Test the following when the resistance is greater than 0.20 Ξ©.
    • Base of the antenna for a poor connection to body ground.
    • The coaxial cable interconnects for a poor connection or corrosion.
    • Test for an open or high resistance from the battery negative cable to the body. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  6. After finding and correcting the condition, operate the system in order to verify the repair.
