Guages and Wipers not working

[FKat 0]

Had a little accident recently involving going up a kerb and through a barrier which wasn't too fun:S But right after, I drove it, and everything was fine, then the next time I drove it again, I had lost all the guages, then it was fine again and then I lost the guages again and I haven't had them back and I also noticed that the wipers weren't working either. So I'm guessing something, somewhere has come loose...but where? Fuses are all ok, and a few of the dash warning lights are still working including the indicator arrows which flash but do not make that clicking sound. Any pointers towards where the problem might be would be appreciated thanks:)
