After washing the car I decided to take a look at why the interior lights were not working. The car was reporting that a fuse had blown but every time I changed it, it kept on blowing.
Also there was no "Always Live" power to the car so the seat did not work when the ignition was off.
I remember that I had some problems fitting the passenger sunvisor, so I took a look at this first... And guess what, I found the problem. The positive wire had split and was connected to the Shell of the car. Is was shorting the car out.
I removed the sun visor and needed to fix that before I refit it.
I also had ordered a new bit of chrome for the front windscreen as it flew off a couple of months ago. It was only 3 quid from Jag which I thought was good!.
