i have a 99 xjr, first , my driver seat do not tilt foward or back(top part only), but do more up and down, slide foward and back. and the pass. seat do not more at all. checked all fuses-ok, need help getting the seats working again.

 

Operation is controlled by a module located under the front edge of the seat. It is easily removed by removing a couple bolts and the two connectors. Test procedure is to swap modules with the other seat and see what happens. If you have two failed modules I would suggest looking for an used one as they are incredibly expensive at the parts counter. Try car-parts.com and remember that used parts prices are fully negotiable. I got one shipped for under a hundred dollars. A common failure point is a circuit board line at the edge of the board that is rubbed by the plastic housing. Many have been able to repair with a small soldering iron.

If that doesn't solve the problem look to the switch pack on the side of the seat. I took one apart and resolved a connection problem .

. . . and welcome to the forum!
