'88 5ksq-Pwr Seat Switch

[msr11@psu.edu (Matthew S. Robinson)]

        Looking for info on the power seat adjustment switch(Joystick and
paddle unit), for a 88 5ksq. My driver seat will not move back (rest of
movements are fine). 1)Looks like a PITA to dissassemble-anyone BTDT?  2)Is
it truly a GM part? If so what models?  How $$$ to replace?

        Memory does move the seat back (fortunately I saved a full back
position)-so I am 99% sure it is the switch...

Thanks for any advice,
Matt.
