Gauges on Left Not Working Tach, Temp, Volt

[Imatk]

I have a '91 Mustang GT with about 200k miles on it.

I am the original owner.

Today the left side of my gauges stopped working.

The Tach, the Temperature Gauge, and the Voltage Gauge are completely dead as if they have no power.

Could this be as simple as a fuse?

They worked fine this morning and this afternoon on my way home from work I noticed they were just not working.

So any help would be appreciated

Check fuse #18. It's the fuse for the instrument panel, among other things. It went out on me a few weeks ago. I lost all the guages except for the speedo (mechanical), I replaced the fuse and it fixed it.

Yep it was that fuse.

I replaced it and it worked for a few days, but it has blown again.

Anyone know why this might keep occurring?

No changes have been made in years... stock gauges etc. ... just started happening.
