Can anybody help me out and tell me where the PTC (electric cabin heater) fuse is? I've looked on every fuse box diagram I can find and can't even see an 80a fuse. I say 80a because other sources tell me the fuse is 80a.
I have the PTC heater fitted (I can see it) but it doesn't turn on using any heater setting (or the MAX button). The car is a 2012 Tit X (2.0 diesel) estate if it helps.
