WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
Memory Switch
- Disconnect the harness connector at the heated/cooled seat switch.
- Test for infinite resistance between the memory switch signal circuit terminal 9 and the switch supply voltage circuit terminal 1.
- If not infinite, replace the heated/cooled seat switch.
- Test the resistance between terminal 1 and terminal 9 while pressing the memory 1, memory 2, and EXIT buttons. Compare the resistance readings to the values in the Memory Switch Values table below.
- If the resistance is not within the specified range, replace the heated/cooled seat switch.
Memory Switch Values
| Switch Position | Resistance |
|---|---|
| Idle | Infinite |
| Memory 1 | 2.03K-2.49K Ω |
| Memory 2 | 3.83K-4.69K Ω |
| EXIT | 8.33K-10.18K Ω |
