The fan probably wasn't hooked in again by the worker, either because they forgot to or didn't know it was meant to be included.
Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
If the window switch is functioning properly but not lighting up, it could be a faulty LED bulb within the switch. You may need to replace the switch to resolve the issue. Ensure to check the wiring connection as well to rule out any loose connections.
By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.
A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it. If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on It may still use power if it is a lighted switch. Find a licensed electrician at www.contraxtor.com
All a switch does is make and break the supply of electricity to the lamp. If you get a chance to visit a science museum ask them to show you a "knife switch". Another place to see one is the Physics Lab at your local college or high school. Once you have seen a knife switch you will understand exactly how a basic switch works. It's quite simple really: a switch is a device which can be used to make or break a circuit. If that circuit carries a voltage which would be dangerous to people or animals then the handle of the switch must be made of a good insulator and the rest of the switch must be well shielded to stop anything else touching any live wires.
The ceiling fan works because it is powered by a separate motor, while the light may not work due to a burnt-out bulb, faulty wiring, or a problem with the light switch.
The issue with your ceiling fan's light not turning on could be due to a problem with the light bulb, the light switch, or the wiring connecting the light to the fan. It is possible that the light bulb needs to be replaced, the light switch is faulty, or there is a wiring issue that needs to be addressed.
There could be several reasons why your ceiling fan works but the lights do not turn on. It could be due to a faulty light bulb, a problem with the wiring, a defective light switch, or a malfunctioning light kit. It is recommended to check these components and consult a professional electrician if needed to diagnose and fix the issue.
If the heater still works the bulb is just burn out. I doubt you can change the light you will have to replace the switch.

There's a switch on the brake pedal that when you step on it, it completes the circuit for lighting up the brake light.
A light dimmer switch works by controlling the amount of electricity flowing to the light fixture. By adjusting the voltage, the dimmer switch can increase or decrease the brightness of the light.
What year is the Ford Explorer ? There could be a separate fuse for the lower brake lights
A pull chain switch in a ceiling fan works by controlling the flow of electricity to the fan motor. When you pull the chain, it either completes or interrupts the circuit, turning the fan on or off, and sometimes adjusting the fan speed.
A light bulb dimmer switch works by controlling the amount of electricity flowing to the light bulb. By adjusting the voltage, the dimmer switch can regulate the brightness of the light bulb.
Power is being interrupted; the turn signal switch is a power juction see if the power is flowing thru it.
