I have two Harbor Breeze celing fans w/remotes and the one remote will not operate the fan or light I have to use the wall switch to turn and turn off the light and the fan does not work. The second one the light won't work with or with out the remote or by turning on the light swirch only the cord operates the fan on one and the light on the other.

Do both fans have pullchains? If so, bypass the remote receivers to determine if the fans work without them.
