96 Chrysler LeBaron Convertible

My 96 LeBaron, 100,000 miles, needs the third oxygen sensor in the last 3000 miles. Any ideas why?



Also, the rear windows have stopped working and I can’t find the motor.

Something is obviously contaminating the sensors. Is it burning oil?

The motors are behind the door panels in the regulator assemblies.

Could be the connector is bad. Every time the sensor is replace the connection is re established for a short time.
