Question about 1996 Jeep Grand Cherokee

1 Answer

Coolant sensor I have a 1996 orvis edition straight 6 jeep. The air or heat does not work, blows out hot in summer and cold in winter. Now the display screen in the middle had an orange bar running acroos the front and "coolant sensor bad" keeps coming up. Does one have anything to do with the other and could it be a coolant level sensor or a coolant temperature sensor, and it is expensive and or easy to replace either? Reading through some of these, my truck also has many of the same issues as posted.

    I have somewhat the same problem, but after finding the sensor, I saw that it wasn't plugged into anything. Any idea where the wires might be found?

Yes inexpensive and easy to change located on the engine block is a two wire sensor threaded into the water jacket, you should also check to see if your heater hoses (both) are hot after 20 min of idling if they are cold you should check your coolant and the lower radiator hose to see if its cold as well if so you thermostat need to be replaced, as for the ac may need a charge ?does this truck have electronic climate control? also how does the temp gage on the dash read while driving ? please rate -jeff

How do I fix the heat


You have one of two problems. The heater core is plugged /
restricted or there is an inoperative internal blend door motor problem. Start the vehicle and let it reach operating temperature. Feel the hoses under the hood that go into the heater core. They should be close to the same temperature. If one is hot and the other luke warm/cold.... the heater core is plugged/restricted. If both hoses are near the same temperature, suspect a defective/non operational blend door motor that controls heat/cold/airflow attached to the heater box assembly

It sounds like the system is fried. Based on the description, it is just pulling in the outside air and not doing anything to heat or cool the flow. Unfortunately, this is a job for your preferred mechanic.

To clarify - - if the truck has rear and heat, you have two heater cores and two evaporator cores. The evap cores carry the freon.
If the leak is in the evap core in the front, the price is probably right.

I have a 2005 GMC Sierra regular cab. 4.3 v6 The heater has only been blowing cold air. Checked coolant and replaced the thermostat. No change. AC worked fine this summer. Heat worked fine last...


sounds like you have a bad temperature door actuator. This is a motor that connects to the door and uses inputs from the sensor in itself and the heater control module to open the door from hot to cold. I does take some knowledge on recalibrating this actuator and installing it. if it isn't install correctly it could damage the new part, so just take care

I am guessing you have not changed your thermostat from a summer one to a winter one. If this is the case you need to put a 195 degree thermostat in to replace the 165 degree summer one. Let me know. Thanks.

The damper door is located on the passenger side, next to the floor board. You can look in and see the door, kind of under the center console, under the dash. This door controls whether the Jeep blows hot or cold air.

Dual cloimeate control blows hot on one side and


you have to get a new control panel which cost usually around 800 dollars. Mine is the same way but i haven't got it fixed i just took out the glove box and kept the switch to tell the motor to make it hot or cold air and put a screw in it and have it held on hot for the winter then ill taker it out in the summer and have it blow cold air

Blowing hot air


The heater valve on these cars are hard to access. If you are trying to get rid of the heat, a quick solution is putting a valve on the heater hose from the outside. Cut the hose and install a valve in which you can regulate the amout of hot coolant going into the heater core. Since its summer you might as well shut the valve once installed. Winter time comes just open them up again.
