Hello Rebecca Jones,
The lift & tilt motors seem to be available... but the forward back seems
RATHER RARE...
You MIGHT WANT TO
JUMP ON THE $85 one below!!
For parts you can check first on RockAuto.com (I'll put a link at the bottom)...
NEVER-MIND ... I checked & got nothing!
Surprisingly... you can also find a really decent selection and competitive prices on AMAZON (I tried to demonstrate)...
Not there either...!!
But first find your part (pix) below... on the web... then look under your seat to see what you recognize... and check your local auto dismantlers (salvage yard).
Then check out
eBay...
If you move quickly... and verify it is good or NOT GOOD
in the allotted time... eBay will protect your purchase...
Found one (see below... $85 free shipping.. good price:
(offer $60)).
If you are like I am... I buy that part... can't wait to start...
but in the MEAN-TIME I looked up my LINCOLN and found a TECHNICAL SERVICE BULLETIN on MY SPECIFIC SEAT issue at
BBB Industries (free tech bulletins & wiring diagrams... registration required)
Hope this helps!!
