The passenger side still works. I checked the fuse that I think it is. That looks good. Is there anything else I can check to see if it is an easy fix (someone who is not mechanically knowledgeable)?

Hi,

I looked at the wiring schematic for the heated seats. Both seats get power from the same fuse, so if the passenger seat works, that isn't the issue. I attached the wiring schematic for the seat heater below.

So, we need to determine if the issue is with the seat heater itself, the switch, or the heated seat module.

Here is what I need you to do. At the seat connector, there will be two wires. One is brown with a black tracer, and one is black with a yellow tracer on it. With the switch turned on, we need to determine if those wires are getting power.

Take a look at the link below. It explains how to test wiring.

Let me know what you find or if I can help in any way.

Take care and Happy New Year,

Joe

Suggested Repair

Because both heated seats share one fuse and the passenger seat works, the fuse is not the cause. With the switch on, check for power at the driver seat connector on the brown/black and black/yellow wires to isolate the heater element, switch, or heated seat module.

Conversation Summary

The driver seat heater on a 2017 Volkswagen Jetta no longer works, while the passenger seat still heats. The owner checked the suspected fuse and it looked good. The expert explained that both seats are powered by the same fuse, so a working passenger seat rules out the fuse. Next, with the switch on, power should be checked at the seat connector on the brown wire with a black tracer and the black wire with a yellow tracer to determine whether the fault is the heater, switch, or heated seat module.
