Their is power but nothing is functioning no up or down no lumber no back or foward motion please assist if u can thanks in advance
Did you test the switch ? If there is voltage at the switch use a volt meter an see if there is voltage coming out going to the seat motors !
Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.
if you have power at the seat switch , the switch is bad or the seat motors . You need to do some voltage testing !
Body control module perhaps bad
SOURCE: rear heated seats workin,front is not fuse is good
Check the ground at the other end of the heating element.
SOURCE: escalade gear oil
Depending on which front axle, "F" axle is GM part #12378261 75W90 Synthetic gear oil, must meet GM spec 9986115
"S" axle is 80W90 gear oil GL-5 spec. I dont know how to tell you to ID which axle you have so I would recommend using Synthetic oil for both front and rear axles.
The rear axle is same as the "F" axle lube as above.

a relay controls the heated seats then linked to a circuit breaker instead. the relay is more than likely the problem
