...When turning R/H corners, it makes a clicking or knocking sound.....

That sounds like a problem with the CV joints, Rob, and the usual procedure is replacement rather than repair. It's a fairly serious issue, though, and one which shouldn't be ignored for too long - the noise is caused by wear, but is often followed by complete failure, which can leave you stranded.
The price sounds within reason for that repair, so it's your call.

The minor problems may be even more minor that you think, as a blown fuse could account for the errant dashboard lighting or the lack of air conditioning - not saying that's all it could be, but perhaps worth checking out, as it might influence your decision on repairing the CV joints.
I'm of the mind to keep an older car as long as my wallet stays in good condition similar to that of the car. A 13 year old Subaru shouldn't be going to the scrap yard, yet. My Mazda is only a year newer, and I hope to keep it for at least another 10 years.

Thanks, Wayne. Yes, I'm getting a little spooked by this problem, so will try to get fixed asap.

I think the AC problem is due to a compressor that has died. Still thinking about this...
