I experienced my car's gauges on the left side temp/oil pressure/fuel working intermittently - changed fuse #9 even though it looked ok and the gauges have behaved since.
My experience with fuses on this car is that even though they look good, there may be hairline cracks on them resulting in intermittent problems.
I used to experience intermittent loss of my aux fan and radio/clock/dome light.Both of these problems were also attributed to faulty fuses looking OK.
Ever since I swapped out ALL the fuses in my car with the fuse upgrade kit, no intermittent power problems at all.
My 2 cents, for what it's worth.
