The blower resister is not supposed to be grounded. The smoke may be steam from a leaky heater core.
A leaking heater core. oil is leaking on the engine and is burning and beining drawn in by the vent or the blower motor is going out Are you sure it's smoke or is it steam? If your windows are steaming up and it smells like maple syrup , your heater core is probably leaking.
If the smoke is coming from the electric fan itself, then it needs replacing. It could be the smoke is steam that the fan is drawing from the radiator, and you have a coolant leak at the radiator.
No you cannot smoke before a PET scan because it will alter the results and it will be detecting in you system which may cause problems with the scanning process.

Excess fuel causes black smoke.
If the a/c compressor cools the air coming from the vents, and the heater knob makes the air hot, but the fan switch doesn't change the speed of the air coming from the vents, most likely the culprit is the fan switch itself, the blower resistor, or the blower motor. With smoke being present, there's a good chance the blower motor burned up.
Because without the resistor, there would be a short from the base to ground, and sometihng would smoke.
Resistor have a definite function in circuits and because every resistor disspates power, it is not included in the circuit without good reason. Some smoke detectors have electronic circuits in them, and these would have resistors, but it is not possible to be more specific.
Blower motor may be burning out.
Human can cause pollution by trash throwing trash in the lake or on the ground or by in type of fuels or smoke or gas in the air this is call air pollution but smoking and gas form disels can cause pollution and can be bad for the ecosystem and they can also cause it by throwing all the trash they throw down on the ground help people and stop throwing trash on the ground.
The only way a bumper can create smoke is is it is trailing on the ground. There are no 'mechanical' parts in a bumper. The end of the tailpipe is probably located right under the bumper and what you are seeing is smoke from the exhaust system. You should have the vehicle checked out as smoke from the exhaust is usually not a good thing.

Cigarettes can cause more than lung infections. They can cause cancer, and even death. Cigarette smoke is just as bad as smoke from a fire, and with cigarettes, you are inhaling that smoke. The smoke from the cigarette can also cause cells to die, which is not good at all.
