Rear Wiper Will Not Stop!

I am very familiar with the Alarm component issue; replaced it 50k miles ago with a factory new one. This time I ordered the Fujitsu relays and had an electronics shop replace them for me. When I installed it, the rear wiper worked in intermittent mode for about three sweeps and then worked continuously and would not shut off until I turn the ignition key to the off position. Are there any other components on the Alarm assembly could fail and cause this continuous operation?

Thanks.

This one confuses me. I replaced the relays in mine a couple years ago. Everyhing works fine except with the washer button, it will keep running until I hit a good sized bump. Works fine if I just use the wiper button though. Some day I might have to dig into it deeper.
