I'm not saying the frame was spliced, but my step-nephew talked my brother into buying a lincoln continental, beautiful car, 2 maybe 4 years old, and the AC didn't work well. I tried recharging it, measuring the output air temp, didn't help. Eventually a mechanic found that the air duct under the dash, I guess, wasn't connected to the next air duct and I guess the cold air was leaking out of the cabin. I presume it was in some big accident.
