Ceiling fan is 18 years old but would still like to repair if possible. Remote will not turn on lights or fan, but the red light on the remote lights up every time I push a button. The fan will try to come on and sometimes does if I flick the wall switch real fast. Sometimes the lights will flicker when I do this, but they never come on. Is this a remote control problem or something wrong with the unit? Thanks...it is a Harbor Breeze
