I too have a burned chemical smell in the cabin of my 04 Silverado (226000 miles), it began about two months ago. I can hardly stand to drive it. At first I thought the blower was picking up exhaust under the hood, but that is unlikely. Besides the smell is not of exhaust, but rather I imagine vapor from a chemical dripping on the hot engine or exhaust. If anyone has any ideas of what to look for, please help.

Any brake work lately? Fluid being squeezed from caliper out reservoir is a possibility. Power steering fluid. Look for trail leading to exhaust. A sweet smell is antifreeze. Check and monitor all fluid levels. If any are low that is suspect.
