As per the title, the heated rear window and the rear parking sensors do not work on my 2007 V8V. The led lights on the switches for both do come on but that is all. It seems to be more than coincidence that both are out of operation, so anyone have any ideas?

At a guess it's a fuse, not sure if both items share a common fuse though, maybe someone else on here will be able to tell you.

According to the 2007 wiring diagram.
Relay 4, fuse F14 is PDC module. (Fed by CEM Fuse 54
Relay 7, fuse F3 is heated rear screen.

Thanks for the input both, it's a good shout. It's a little late for me to go & have a look now, so I will have a go tomorrow and report back.

Looking at this it's unlikely (but not impossible) that you have popped 2 fuses, but still worth checking.

I had a weird one a few weeks ago, I pulled fuse 22 to open up the exhaust, then noticed when my phone rang in the car a few days later that I had no hands-free feed, whoever fitted the Parrot kit prior to my ownership of the car, must have decided to feed it off the same supply!!

Update - both fuses turned out to be ok. Heated rear window issue seemed to be where the spade terminals on the screen connect to the loom, just a little 'corrosion' I guess, as the problem disappeared after moving the spades around a little.

The parking sensor is probably a duff sensor. I've another on order, so will know for certain once I've replaced it. By the way, all the reading I've done indicates that you need to get the bumper off to change the outer sensors. My hands aren't necessarily small, but I managed it without removing it.
