I get them to return by using the wiper wand to move them a tap at a time. I was told that the relay is behind the fuse panel over the tunnel. All I have behind my fuse panel is the flasher relay and the service engine relay ( I just intensionally shorted that turkey to turn off my "Service Engine" light that came on at 81 K miles. The relay # I got from George at RDS is AMR2341 (it is red) - George didn't have one so I bought one from RN. They both felt that it should be behind the fuse panel. I went to install it today - no can find! Thanks in advance for any help.
There is no relay for the wiper on the 97, as posted earlier, it is controlled by the body ECU.
The problem you are having is caused by a bad park switch on the wiper motor. Rover part # 520160.
Remove the wiper motor cover and locate the park switch on the wiper motor (its that white-ish thing the wiring harness plugs into). Lift the LH most edge a bit and slide it off to the left. Swap the wires to the new switch and slide the new one on and everything will work 100%.
No tools needed other than a screwdriver to get the wiper motor cover (dash) off.
The AMR2341 is for the 93 110 or the 94-95 D90.

The cause of this is usually the drum that goes on the wiper drive shaft. It connects to the shaft (the part coming out of the bulkhead) by use of a set screw. They loosen up over time. In some cases you can just tighten the set screw and it will be good. In most cases the set screw is rusted in place and you have to drill/ grind off the drum and install a new one. They are cheap but getting them off is a PITA sometimes.
Grab the wiper arm and move it back and forth carefully. If you see the arm and the splined drum moving, but not the chrome shaft coming out of the bulkhead then you need to tighten that set screw.
In later models they did away with that goofy system. I used to have to change those drums every couple years after Maine winters.
