SOURCE: Bosch 02 sensor downstream on

The two white are the heater
The black the ground
The gray the O2 Sensor output,
you back probe to check Voltage
& Switching Times

The vehicle wiring harness does not have to match
the sensor, BUT -- you need to have the same
connector on the sensor

If you have a universal cut & splice, you have junk,
and we given the wrong part

Get a Bosch or NGK, OEM sensor & just
plug it in

Fan relay is located under pass headlight. Remove light assembly, use 2 1/2 " hole saw to drill hole in plastic housing ,3"from back wall, 3'' from left side.This will put you right over relay. Unscrew two bolts,replace. Relay was $40.... dealer wanted$350 to remove front bumper to replace it.

Radiator fan not working replaced relay,temp switch and fuse fan works if hot wired it's on a 2001 jeep grand cherokee


Check the wiring from the relay to the fan motor, and check the wiring from the fuse block. Basically check all wires that supply power to the fan motor, use a volt meter. Fan Relay (behind headlight, under battery) on the 2001 GC 4.0L are a piece of ****, I change mine almost yearly. The problem is their location, a high heat area prone to the elements. I understand that 2002 and newer, the location was changed and the problem solved. Relay might close the circuit when cold or at reasonable temps, but might open a circuit when it heats up, causing the problem.
