I reclined my drivers seat (pull up on manual level and lean back). When I pull up on the manual level and lean forward the drivers seat will not return to the upright position. Appears to be stuck in the reclined position. Had a friend attempt to push the seat up from behind as a pulled the manual level up but the seat will not move. Has worked fine with no occurances of sticking in the past. Can i manually release the catch under the seat to return the seat to an upright position?
