Hi, I am having some trouble with the front middle seat in the FR-V. The seat seems to be completely jammed and will not slide forward or back. I have tried using the lever on the front and the one at the rear as in the manual but it will not budge. Having looked underneath I can see the lever does move some mechanism when pulled. I'm not sure if I'm doing something wrong or the last owner sold it to me like this as I never checked it at the time of purchase. The back middle seats slides fine. Any advise will be greatly appreciated.
