Where are the windshield wiper relays located in my xc70?

[brian c]

The windshield wipers on my 2004 xc70 is doing weird things only on high speed. They move slow or stop randomly. It also happens when I use the intermittent mode but only when high speed kicks on. I replaced the relay in the fuse box under the hood but is there another one somewhere? I want to check the relays before pulling the motor.
