i'm wondering if a rerun of ghost whisper will air again and if so time and channel?

Reruns of Ghost Whisperer are on all the time, If you are living in America you can catch it on ION, WEtv and Syfy. ION schedule :link WEtv Schedule: link Unsure about Syfy but I'm sure you can catch the latest times on your TV guide. I hope I helped you with your Query :)

For me, the channel is 305(ION television) the episodes usually don't come on on Sundays....
