I have a 2004 Chevrolet Avalanche. The Driver Seat stopped moving by the controls on the side of the chair. When you put key #1 in ignition, the seat will raise up to where it is supposed to be.

You may have memory seats, your owners manual should have some info on setting memory.
I looked at wiring diagram for your power seat, driver side, it showed three seat motors depending on what your trying to do? If the seat won't move forward and back, have to check horizontal seat motor. The fact that one of the seat motors is working tells me voltage and ground to the seat switch are ok. Could be a seat motor or the control switch problem? I'd have to do testing to decide which?

SOURCE: power seat, driver side

If only one seat is not working the fuse/relay is ok or both would not work, most likely cause based on experience is the control switch, then the power seat motor.

SOURCE: 1995 BMW 525i seat height motor works on one side of seat only

there are 2 cables that come out of the motor that operates that feture. Over time the outsdie tube of the cable streaches, causing the cable that turns inside, to come out of the transmission is drives. One way to fix this is to remove this cable and shoren the outside tube by cutting it, and then re-insall back into the transmission. This is a 50/50 chance repair. The correct way to cure this issue is to replace the lower seat frame. $$$

I have and 04 avalanche and the seat is stuck ! I

There is a small cable on each side of the the seat, they are covered with a hard plastic cover. If that cover breaks, it will let the cable come out. When one side of the seat gets off track from the other side , it wont move. The cable is flexible, the cover holds them straight. The cover is either a dealer item or junkyard.

2004 Chevrolet Avalanche driver side heated seat switch with pedal adjustment and memory does nothing.

Is it just the heated seat? If it is the element in the seat pad has shorted out and the switch acts like a circuit breaker and will turn back off after a few seconds. The only way to fix it would be to pull the seat cushion and test the leads to the element with a meter for resistance. Once the pad is replaced or repaired the switch will work as normal again. There is nothing wrong with the switch...It is the heating element in the seat.

Power seat moves back and forth each time key clicked to unlock car doors. It doesn't stop moving until I manually touch the seat power button.

your seats have a MEMORY stored with each key

use your seat control button to reprogram the seat

however, you need to know if the key you have is the primary key or secondary

first program as driver one and then use the key
if seat moves then program as driver two

if however... you mean that the seat is always moving, AT ALL TIMES, and you ALWAYS have to readjust with the seat switch then you probably have a module concern

Heated, power seats not working

Check wiring under the seat. Frequent habit of pushing things under the seat such as flashlights and tools etc and moving the seat forward and back sometimes pulls wires or breaks them.
