Hi Tllandbll:

I have something that may help you on this one. Check out the link below. It is an exploded parts view of your faucet.

Just need to shut water to faucet, remove handle assembly , pull off spout and reach in back for the diverter.

If need replacement part MOEN will replace free of charge (including free shipping costs). Just call 1800BUYMOEN, give model number and tell them what part you need...free shipping takes up to 10 business days to get to you. For $12.00 they will ship the part to you in two days..guaranteed!!

Let us know if need more information... Mark
