If it is the radiator fan check the relay connected to the thermostat. If it is the dash fan check the relay system under the hood, and possibly behind the glove box for a blower relay.

Where is the radiator fan relay in 1995 cherokee 4.0L inline 6

most 93 to 95 have viscus clutch not electric fan (A/C evap fan sure) but some do have the Aux fan too. and the PCM reports DTC errors, if the relay fails. did it? report that?
ok the 95 XJ with 4.0 does have fan.... have FSM in hand.
If the ECT has air pockets it well never report hot temps.
it will not energize the Fan relay if the ECT fibs. for any reasons.
page 35 Chapter 7
the viscous fan locksup at (165° to 180° F).
the electric fan is as follows.
i guess you never looked in the PDC before or its lables
"The fan is controlled by the cooling
fan relay, which is located in the power distribution
center (PDC). For the location of relay within
the PDC (Fig. 41), refer to the label on PDC cover"
and now AUX Fan , quote2.
"When coolant temperature is above 88°C (190°F),
the powertrain control module (PCM) provides a
ground path for the fan relay. This ground is provided
through pin/connector #31 of the PCM 60-way
connector. Battery voltage is then applied to the fan
through the relay. When coolant temperature is below
88°C (190°F), the PCM opens the ground path to
the relay. This will prevent the cooling fan from being
Whenever the air conditioning is operated, the
PCM engages the auxiliary cooling fan

given these facts? why not turn on A/C and end the guessing.

I use my scan tool , and innova 3140 for jeep OBD1.
it shows me what he pcm sees for ECT readings
if the engine is at 100C and the ECT shows way lower
its bad. or has air pockets around it,
no ect runs in air and works, none,.
if say the ECT is at 100C and the fan relay is not closed
the relay is bad or ECU driver to it blown. (bad ecu)
if the relay coil is hot, and the fan is not the relay is bad.

if the relay is closed and 12vdc out of it, then fan is dead.
if the fan is good (hot wired), and the relay out is hot , the wires are bad from relay to fan.
a $10 voltmeter and the guessing ends.

The fan comes on in my 95 Jeep Cherokee at all speeds but there is no heat. The carpet is dry beneath the heater core, no fogging of windows when started and no smell of mildew. What could be the problem?

Your heater core mite be plugged. you can buy flushing kits and hook too a hose and back flush system. Also the electrical valve could be in closed posistion.

Power windows won t work

There are broken wires in the wiring harness between the frame and your driver's side door. These wires control all the windows and door locks in a 95 Jeep. Same thing happened to me. You will have to cut the rubber boot to get it off and check which wires are broken and repair them.

Trying to locate an electric fan motor for a 1998 grand cherokee 5.9litre

You want a fan motor from a 93-95 taurus or sable.

The fan connects to the motor differently so you will want to get a fan/motor assembly from a junk yard (I spent $15). You will transfer the plastic fan to your jeep. You can use either the old motor or get a replacement for about $70.

One other thing - the taurus/sable motor has a different electrical connector so you will need to do some splicing.

Total job took me about 15 min
