The process appears to differ between the 2000 and 2003 so AllData likely won't help.

There is an adjustment lock on yours which is located at the throttle body.

1. Disengage the adjustment lock on the cruise control cable by pulling the button wings rearward (DON'T REMOVE THE LOCK).
2. When the lock is disengaged, the cable will move freely in and out of the adjuster body.
3. With the throttle body CLOSED, take the slack out of the cable.
4. Firmly press the adjustment lock until it is fully seated.

You should be good to go. In later years, slack is automatically taken up inside the cruise control module.

I thought the heated mirrors came on when you activate the heated seat. I will check my manual tonight.

No. Especially since not all cars have heated seats.

THX I am getting old and cannot read very well.

Only on pre-2000 models. The 2000+ are completely electronically controlled. There isn't even a vacuum line running to it.

the adjustment lock was loose, causing the cable to move a good 1/2" without moving the throttle plate. all fixed now. must have done that last time I had the TB off

Excellent! Check one off the to do list...
