WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Memory Seat Feature Inoperative

Step Action Values Yes No
Schematic Reference: Driver Seat Schematics 
Connector End View Reference: Power Seat Systems Connector End Views 
DEFINITION: One or more of the memory recall functions are inoperative.
1 Did you perform the Power Seat Diagnostic System Check? - Go to Step 2  Go to Diagnostic System Check - Power Seat Systems 
2 Attempt to set and recall memory 1, memory 2, and exit seat position settings.
Does the system operate normally?		 - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems Go to Step 3 
3
  1. Install a scan tool.
  2. Observe the Memory Switch parameter in the driver door module (DDM) Inputs data list.
  3. Press the memory 1 switch.
Does the scan tool display the memory 1 switch as Active only while the switch is pressed?		 - Go to Step 4  Go to Step 6 
4
  1. Observe the Memory Switch parameter in the DDM Inputs data list.
  2. Press the memory 2 switch.
Does the scan tool display the memory 2 switch as Active only while the switch is pressed?		 - Go to Step 5  Go to Step 7 
5
  1. Observe the Memory Switch parameter in the DDM Inputs data list.
  2. Press the EXIT switch.
Does the scan tool display the EXIT switch as Active only while the switch is pressed?		 - Go to Step 12  Go to Step 8 
6
  1. Disconnect the memory switch connector from the DDM.
  2. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 1 switch signal circuit terminal in the switch harness connector. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  3. Press the memory 1 switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 13  Go to Step 11 
7
  1. Disconnect the memory switch connector from the DDM.
  2. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 2 switch signal circuit terminal in the switch harness connector. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  3. Press the memory 2 switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 13  Go to Step 11 
8
  1. Disconnect the memory switch connector from the DDM.
  2. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 1 switch signal circuit terminal in the switch harness connector. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  3. Press the EXIT switch.
Is the resistance less than the specified value?		 0.5 Ω Go to Step 9  Go to Step 11 
9
  1. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 2 switch signal circuit terminal in the switch harness connector. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
  2. Press the EXIT switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 10  Go to Step 11 
10 Test the memory switch signal circuits in the switch harness for a short to ground or voltage. Refer to Circuit Testing in Wiring Systems.
Are either of the switch signal circuits shorted to ground or voltage?		 - Go to Step 14  Go to Step 13 
11 Inspect for poor connections at the memory switch connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 17  Go to Step 14 
12 Inspect for poor connections at the driver seat module (DSM) connectors. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 17  Go to Step 15 
13 Inspect for poor connections at the DDM connector. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 17  Go to Step 16 
14 Replace the memory switch. Refer to Heated Seat Switch Replacement - Front .
Is the repair complete?		 - Go to Step 17  -
15 Replace the DSM. Refer to Memory Seat Control Module Replacement .
Is the repair complete?		 - Go to Step 17  -
16 Replace the DDM. Refer to Switch Replacement - Door Lock and Side Window - Driver in Doors.
Is the repair complete?		 - Go to Step 17  -
17 Operate the memory seat system to verify the repair.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
