SOURCE: 2005 LeSabre check engine light on due to evaporative emissions

Finding a leak in these emission systems is almost impossible.
All it takes is a pin hole in a hose to screw up the whole system.
The best way to find the leak is to take and have a smoke test done on it. Smoke is injected into the system and where ever the leak is , the smoke will leak out of it. It's faster and more reliable then replacing hoses and other things you don't need. Call dealers, or repair shops to see who does smoke tests.

Have 2001 Buick LeSabre with Check Engine light. Disconnected the battery and the car won't start. Dashboard lights come on but car won't even turn.


Why would you disconnect the battery?

Do you have a security light on or flashing when you try to start it?

2001 buick lesabre-ac problems


  • Assumed your AC unit is OK, but uneven temperature distribution. Try to throw the heater on an off severtime. A sticky valve on the heater would cause similar problem.
  • Observe the RPM while parking your car. While the AC cut in cut out (or turn on an off). If it cause no load on the engine. The freon may be low or the compressor is bad. In this case only the intake side of the evaporator is cooler than the other side.
