I do not have info for 2006 models. The following fuses protect power mirrors circuit on the earlier models.

2002 Avalon XL & XLS: ECU-ACC Fuse 5A - driver side (behind left side of the dash)

2003 Avalon XL & XLS: ECU-ACC Fuse 5A - driver side (behind left side of the dash)

2004 Avalon XL: ECU-ACC Fuse 5A - driver side (behind left side of the dash)
2004 Avalon XLS: Gauge 2 Fuse 10A - driver side (behind left side of the dash)

Just open fuses box on the driver side (behind left side of the dash), pull off these two fuses one by one (starting with ECU-ACC fuse), check for continuity and replace with the same rating. You will find fuse locations on a label attached to the inner side of the fuse box cover.

Hope this info will help.
