It's bad quality PCB! Ford should recall the instrument cluster for 2003-4 models. Googled and found a UK forum with thousands complaining about Ford Focus clusters. The problem seemed to be the same for all owners, and it's corroded PCB (printed circuit board). Did what that forum suggested. It worked!!!
How to fix it:
1. Buy a electronic contact cleaner ($5) from pepboy
2. Disconnect battery
3. Take out the instrument cluster. Need to disconnect two cables. Took a couple of minutes to disconnect the second, the black thing is the key. Needs loosen 7 bolts first, then loosen additional 5 to expose the PCB.
4. Spray PCB the hell of it.
5. Bring in home and dry overnight
6. Re-install cluster
7. Re-connect batery cable.
8. Done! Good luck! Less than 30 min hand work in total.

To get a 2003 F-150 Truck to start after replacing the instrument cluster the cluster will have to be re-programmed. A dealer or possibly a locksmith can reprogram an instrument cluster.
It depends on what you did to the car.
The power or ground connections to the instrument cluster could be bad. Check the fuses, then the wiring to the dash to find a common problem for the heat, gauges and speedometer.
