Yesterday, my 1996 Avalon (198,500 miles) made a shreaking sound from the engine and then the HVAC went off. No AC, no heat, no fan.
Furthermore, the engine, front right, showed a light fuming smoke.
I verified that all the belts were turning (which is the full extent of my automotive expertise)
I drove it home (windows open) and will bring it to the gas station today.
Any ideas on how the entire system would fail and the smoky smell?
