Infiniti FX Heating Woes: Mirror & Windows Issue Explained

Hey there! I had a pretty similar issue with my 2004 Infiniti QX (not too far off from your FX). I'd say I have low experience with car repairs, but this one stuck with me. My heated mirrors stopped working last winter, and it turned out to be oxidized cable connections at the mirror assembly. Took it to my local workshop, and they found corroded plugs that needed cleaning and partial replacement. Total bill came to around 155€, and it's been working perfectly since then. Just to help you better – could you tell me if you're getting any specific error codes? Also, does it affect both mirrors or just one side? This could help pinpoint if you're dealing with the same issue I had.

Thanks for sharing your experience! My mileage is at 183027 KM and it's affecting both mirrors actually. Weirdly enough, I notice the issue is more prominent during cold mornings, but there's no specific error code showing up on the dash just that stored fault I mentioned. I did my last service about two months ago but they didn't catch this issue then. Sounds like your fix was pretty straightforward good to know it might not be something super complicated. Did your mirrors completely stop working or was it intermittent like mine?

Hey again! Yeah, with my 2004 Infiniti QX, it was definitely intermittent at first especially noticeable on those cold mornings, just like what you're experiencing. Mine started acting up around 175,000 KM, so we're in pretty similar territory mileage-wise. The fact that both your mirrors are affected makes me even more convinced it's probably the same issue I had. Mine started with occasional problems, but eventually, they just stopped working altogether. I remember being really annoyed because I couldn't tell if they were actually heating up or not during those intermittent phases. Since you mentioned your recent service, it's worth noting that this kind of issue can be easy to miss during routine maintenance. The corroded connections in my case were pretty well hidden, and you really had to know what you were looking for. The mechanic actually showed me the oxidized parts when they fixed it they looked pretty nasty! Quick tip from my experience while you're waiting to get it fixed, try gently pressing around the mirror housing when it's acting up. If you notice any change, it's almost certainly the connections. That's what helped confirm it for me before I took it in. Want me to share some photos of what the corroded connections looked like in my case? Might help you compare with yours!

Thanks so much for all this detailed info! Yeah, I'll definitely try that tip about pressing the mirror housing that's super helpful. My situation sounds almost identical to what you went through, especially with the intermittent issues on cold mornings. Would love to see those photos if you still have them! I'm feeling much more confident about heading to the workshop now, knowing it's likely just corroded connections and not something major with the electrical system. I'll probably book it in next week and ask them specifically to check the connections. Really appreciate you taking the time to share your experience it's saved me a lot of worry! I'll update you on what they find when I get it checked out.
