I just don't think there are many 2007's with the power passenger seat option.
That price for those parts seems too high for most people. I mean it's not like any of US will be sitting in that seat!

 

partsbill, The web site I listed has the Right side (drivers side from pic) as $552.52 MSRP, but the Left side (passager?) is MSRP for $337.42 and Retails from them at $238.49. Also from the Pics in the parts manauel I have seen the Manaul seat on the passager side has a different wire harness the the power seat. Again this is from this web site that is a "Ford" dealership. I will be calling them today.

So for about $320 for all parts needed, maybe not a bad deal??????
