Re: 99 cavalier Smoke coming out from under dashboard!
Now this may be a long shot... but i had a similar problem on my cutlass. but it wasnt wiring...... it was from the tube running from the head of my engine...... the smell and smoke were coming from hot oil coming out of the crank case vent tube and then being sucked into the air inlet for the heater/ ac.
since a electrical wire's protective cover is petroleum based as is oil.... they smell very similar

This could be a serious problem if the smoke smells like plastic or has a metallic hint ( I.E. You have a metallic taste in your mouth after smelling the smoke).
Remember the old adage " Where there's smoke, there's fire".
If you don't know how to disassemble the dash to find the problem, take it to a shop A.S.A.P. - You could burn up your vehicle by using either the heater or defroster, as they are parts of the same system.
Now for the rear defrost light;
If the light is out but the defroster works, you possibly have a burnt bulb. You'll need to remove the panel the switch is mounted in to gain access to the switch. You'll probably have to replace the switch to repair that bulb.If neither work, then you likely have several electrical issues that need to be repaired.
Sorry to bring bad - ish news!!
the bearing in the blower motor is going out causing the noise and the smell is coming from the blower motor. the parts house will give you the right blower motor for your vehicle make and model and engine size.
If the blower motor is still working, that was not the problem-the strange smell might have been from some bacteria in the plenium, and the smoke may have just been the result of condensation from the evaporator in the plenium-keep an eye on it, but if the blower is working, I would not be overly concerned about it.
