Yesterday I noticed that my seats would not move forward and back(Driver and passenger side). The rest of the functions work fine such as up and down on front and back and recline and headrest. The only trouble I ever had with them before was that one time I believe they stopped working altogether and I could not find a problem and then they came back by themselves. This time seems different though since they partially work. Is there something I may have touched underneath the seat or dash that would affect only the forward and reverse directions on both seats? I did a search but did not find anything related. Thanks
