Ok so when I bought my truck I had the check engine abs and brake lights on with no working speedo. So I changed the vss two times, first a Dorman brand, then standard. Still the system worked intermittently after that.

Now my speedo will only work if it's raining outside, all 3 lights are still on on the dash. The speedo will never work in dry conditions anymore. What else can fix this.

Time to chase the wiring harness from the back of the truck forward, check any plugs and make sure the terminals are not corroded. Other opt's are pcm and or instrument cluster, possible tone gear in the rear diff.
