Evening all, sorry if this has been done to death but my drivers seat heater has stopped working, the cars light up on the switch briefly then go out, passenger seat works ok so I'm guessing that rules out the fuse

Sounds like the wiring to the drivers seat or the heating element(s) are too high resistance or open circuit.

You need to physically and electrically check the wiring and the resistance of the heating element(s).

Read the Error Log.

Wirings good, horrible feeling it's a burnt out element

? As in code reader for fault codes?

Diagnose Tool Like obd 11 or something Else.

The heating is Managed by the BCM

Checked today no code errors 🤦

Take multimeter and Check Heating resistor

👍

Check the wiring/connector hasnt been pulled by accident. Had similar problems on a volvo and the wiring had been caught by something under seat from the rear.

Checked that budd, it's fine 👍

Does anyone know how to check the elements? The wire colours and the expected resistances? Had a quick look this morning, seat out job for me and get to anything and the wiring is all really tight and inaccessible

Don't know why I'm bothering to update as help seems few and far between on this subject, checked what I assume to be the correct wires from the base heater and back heater and I'm getting 2.0 ohms and 3.2 so my guts telling me it's the thermostat in the base heater that's toast, will report back if I get to the bottom of it, so you don't have the same grief as me 👍

Fault found! Scanned with my friends code reader and the seat seems to have tripped out, deleted the code and it's working again, the fault was heat temperature sensor short circuit so if it happens again it'll be the base pad need changed as this has the thermostat in it
