GMC Repair: 2002 Envoy SLT, wont move, side seat

Question
My drivers side seat will no longer move. The seat heater works as well as the lumbar and the seat will lift and lower, but the whole seat wont move forwards or backwards. also when the #2 key controller is being used the reverse-curb mirror feature only pops, they work fine w/the driver #1 controller. Any suggestions?

Answer
the seat is the switch and the the back and forth/ I dont on the fob/ The suggestion that I have is change battery or replace the fob it may be not getting the contact like the first oneIf you need anything further let me know on collision repair advice.com   thanks
