Mercedes X Klasse rear window heating not working

I had a similar issue with my X Klasse. Check your battery's voltage. A weak battery can cause all sorts of electrical gremlins. Have you had the battery tested recently? Also, are there any other electrical systems acting strangely?

Thanks for the quick response When you say 'similar issue', was it specifically the rear window heating, or was it more general electrical problems Knowing if it was the thermal window directly would be really helpful

Yes, it was the rear window heating specifically. After checking the battery, the issue persisted. I would advise you to take it to a workshop.

Understood Sounds like I'm heading to the shop then I appreciate you sharing your experience with the heating coil issue Hopefully, it won't cost me an arm and a leg to get this window demister fixed From what I've gathered, the defroster repair could be around 290€ Thanks again
