If the seat will not move properly with the control switches this may be an issue with the control switch itself at fault or the wiring becoming disconnected at the switch or seat causing this here.It may also be due to a fault with an ecu internally that controls the seat.The first thing that needs done here is to check under the seat and see if anything has become disconnected needing reconnected or repaired.If a fault is found it will need corrected.If this is all checked and found to be o.k. let me know so we can continue.

I apologize for any delay and posted as soon as I saw your question myself.I am on Mountain time which is one hour above west coast time.I will be here until about 3 pm Mountain time today and back again tomorrow around 6 am.If this will not work for you let me know.
With the issue you have here this sounds like the left side of the seat track is jammed and may have a broken component inside of it to where the track itself needs replaced.I have had to replace several of these seat tracks before for this issue here.If you do not see any debris in the track in some cases pushing or pulling on the seat when trying to move it will free up the seat but if this does not work the seat will either need removed and the track inspected to see if it can be repaired or the seat track replaced.I can say in most cases I have had to replace the entire seat track for the same issue you see here.
Unfortunately after looking through all of my info I dont have detailed enough pictures for inspecting the seat track.I will post the seat removal procedure on this here and once it is removed you will want to look at the seat track for anything that needs repaired if it can be repaired.If it needs replaced unfortunately my info isnt showing this detailed info as well.I do show that from a dealer the seat track is $1370 without memory seats and $2000 with memory seats and 2.0 hours labor to have replaced.I know that it usually bolts to the seat bottom with 4 to 6 bolts.
O.k.,if you need anything else from me let me know.
