How do you fix a power antenna that only makes a clicking sound on a 1989 Honda Accord EX?

the drive cord could also be broken inside the drum that holds the drive cord when the antenna is down. If that is the case, you will have to remove the cover next to the motor and remove the broken piece. I believe you can simply replace the antenna mast; eBay has one but it is for a power antenna that mounts on the passenger side.

that means that the drive cord is stripped, on some cars, the mast with the drive strip alone can be replaced, on others, you have to replace the entire mast / motor assembly.
