Could be that somebody lubed up the speedo cable. Is there mechanical aftermarket gauges? Maybe a leak there?

Like the others have stated, it can only be a small number of things leaking on the left side of the dash.
1. Most likely, since you said you were having issues with your speedometer cable, is that something is malfunctioning causing transmission fluid/oil to wick up the speedometer cable into the back of the gauge cluster. Remove the instrument panel and check fitment of the cable as well as the connection at the drivers side rear end of the transmission for any mis-alignment or damage to the speedometer cable itself.
2. Mechanical gauges, which you said that you do not have installed. Anyone else with this problem will want to check these first, as a mechanical oil pressure gauge for example has a hose with pressurized oil coming into the back of the gauge. If you for sure don't have any mechanical gauges installed, don't worry about this one.
3. The brake master cylinder/booster could possibly be leaking near the pedal. Look around the base of the brake pedal while pressing the brake pedal for any fluid leakage to test, or you could also monitor your brake fluid level over time. If this were to be the case, the entire system can be removed rather easily. Disconnect the brake lines from the master cylinder (don't drip fluid on your paint!!!) and disconnect any vacuum/electrical connections from the master cylinder/brake booster. Then remove the (4) 9/16" (I think) nuts from the interior firewall near the pedal assembly, and simply pull the entire brake booster on out through the engine compartment. Replacements can be found in junkyards/ebay pretty easily.
Let me know if you have any questions.
