I bought a pair of Sport seats from a 2004 GT3 with 5,000 miles & installed them in my car. Everything worked great for about 3 months until I used the upper manual lever to move the back rest forward & it jammed in that position. I removed the leather seat upholstery & the cable is still properly attached, so it seems the electric motor at the recline hinge has jammed. Anyone dealt with this before?? Meanwhile the exact same issue has happened with the passenger seat!
