Electric mirrors blowing fuse

[cmm303]

Thank you all for your advice and suggestions.
Today I finally resolved the issue. Having narrowed it down to the blue wire I began at the fuse box and following it to the first connector, x05 on the wiring diagram I unplugged the connector, however turning on the ignition it still blew the fuse.. therefore confirming it was a short in the wiring lume from the fuse box to connector. To confirm I cut the blue wire at the fuse box and at the connector and using crocodile clips bridged a new live connection and hey presto all worked fine with no blowing fuse.
So to finish the job I soldered in a new blue wire and shrink wrapped insulated the joins. The old blue wire was left in situ but fully insulated against any shorts.
I also returned the stereo back to running on the same fuse as the cigarette lighter and mirrors.
All serms to work as it should now, I guess only time will tell.

Excellent news. Persistence paid off. Always satisfying to know that you isolated the problem.

Thank you. Hopefully should another experience a similar problem with either the mirrors, cigarette lighter or stereo it will help resolve the issue.

Thought I would update my post having now found possibly the original short in the wiring loom.
Upon removing the rear side panel to access the transformer powering the two pin AC/DC socket I found the original earth (black wire) melted to the live. I could not believe how thin the earth wire was it must have been no more than 5amp.
Not sure if this was the cause of my mirrors not working as I fixed it by replacing the blue wire but it definitely had an effect somewhere. It's been 4 months since my repair and all seems fine to date.
