Just checked my manual, but my car is a 98, and my manual covers 97 and 98 CR-Vs only, so I don't know how much help this will be for you.
According to my FSM, there is no shared circuitry between the interior lights and windshield wipers, except for fuse 41, but fuse 41 (100A) powers everything except the starter, so you'd have nothing working if that fuse blew.
The rear wiper is controlled by an integrated control unit, which mounts to the back of the main dashboard fuse block. This could be to blame for the rear wiper, but it also controls the front wiper intermittent mode, so that would probably be broken too if the integrated control unit is broken.
The interior lights are not connected to the integrated control unit, but the circuits for that are simpler.
Never underestimate the possibility of coincidence. Modern cars have so many parts, that they frequently have simultaneous unrelated failures, either because of unusual vibrations, like speed bumps, or sympathetic voltage changes, or something else.
I'm attaching pics of the wiring diagrams from my FSM, in case that helps you.
