Hello my dear technical wizards,
Here's the problem I have:
The passenger seat isn't heating, while the driver seat is working well.
This is what I've done to check what could be wrong:
- When turning the rotating heated seat switches, I can hear a click somewhere near the fuse box or under the steering wheel. Anyway, there's a relais switching on, which seems good news.
- When measuring the green connector (what a *** to loosen with the seat in situ! 😅), I can see a voltage of 10.9 V when turning on the switch. This is between the two terminals as shown on the photo. The one in the corner is earth.
- I've also checked the other two terminals, of which one is also earth, but I couldn't get a reading. As I've read that the heating elements are connected in series, I reckon this can't be the problem. Although I don't know where these two terminals are for.
- There's a black 2-terminal connector under the seat too, perhaps connecting the lower and upper heating elements? I've measured for a resistance on this one, which was 1.25 ohm.
Am I right in thinking that, as the seat does seem to be getting electricity, one of the heating elements should be faulty? And as I got a decent (?) resistance reading from the black connector, assuming this is the upper heating element, is it safe to say the lower element must have a broken wire?
There are a lot of assumptions above, so please correct me if I'm wrong. I really do not know what I'm doing honestly.
But if the lower heating element is broken, could it be repaired (I reckon soldering won't last a month) or replaced? And of the latter, where does one find these parts?
Thanks in advance for thinking with me!
Kind regards,
Tim
