If yours has a control valve, it will be inline in a heater hose just ahead of the firewall. before taking it out make sure it has a vacuum line attached. If I remember correctly, default is heat. I hope you checked the vacuum motors on the heater box and made sure that the plenum doors are operating and not jammed while you had it out!!

1995 jeep cherokee heater problems


Get jeep up to operating temp
Turn on heater to max heat
Hood feel 2 heater core hoses goint into upper passenger side of engine compartment firewall.
They should feel too hot to hold
If it's not hot, could be 6 things
1. heater control valve is bad
2. Vacuum to heater control valve is bad
3. clogged heater core.
4. Bad thermostat
5. Bad waterpump
6. Needs more coolant (check when system is cold)

Do these things:

1. Disconnect vacuum line from control valve and feel under valve to manually move valve to open position. This should let hot water flow through core. If you now have heat inside, replace the heater control valve. Or you can disconnect the plunger on the heater control that is hooked on to the silver bar on the bottom of it. With it disconnected you can manually move it to the open position. It will always remain on.

2. When system is cold, disconnect both heater hoses going to heater core. hook up a water hose to one side of heater core and flush out any gunk. When you get done, the water should run clear. If you see lots of gunk come out, that was probably the problem. Replacement is like $20-30

3. When system is hot and engine running, squeeze the upper radiator hose (using gloves) when you release it you should feel a surge of water. Proves your water pump is working. If no surge, check thermostat. If thermostat checks good, look at the weep holes at the bottom of the water pump for traces of antifreeze. If you see a trace or stream of coolant, indicates bad pump.

4. As far as testing the thermostat, watch as your engine heats up on the gauge. when it gets to a certain point you will see the temperature rise, then lower, then rise again. This means your thermostat opened properly, cooling the system temporarily, then heated it back up. Replacement is around $5

Try these and see how it goes.

The heat in my 93 talon dont work. the fan blows, and i have flushed the heater core. still no heat. it is getting cold in kentucky. please help.


If you have flushed the heater, I assume you did this by removing the hoses from the thermostat housing. If there's still no heat, check

1. the thermostat is actually present. If not, put one in. If the radiator core is in bad shape, or blocked, replace the radiator.

2. the thermostat is not jammed open. If so, replace it and use a new gasket under the cap.

3. Verify that the water pump belt is not loose.

4. Remove some dash panels to get access to the heater core valve. Check that the valve is actually turning when you adjust the dash control.

Heater wont work


Could be the diverter valve. It's the one located near the firewall2_bing.gif in the engine bay. The valve is in-line on one of the two coolant hoses that run through the firewall2_bing.gif. Have a helper rotate the temperature knob back and forth, with the ignition turned on, and you watch to see if the valve is being adjusted. I'm guessing it isn't. Sometimes the cable pops off its perch, other times someting is broken on one end of it or the other. Plastic parts are often used in this assembly. Best of luck

No heat


One or more of:

1. Your coolant level is low

your heater hoses to your core are either bypassing the core or the valve is not working and stuck in the closed position.

Heater doesn't work. A/C works and air blows, but no heat. Flushed antifreeze and replaced thermostat already. Help.


There are 3 possible cases: 1- The Flap Divert air direction valve for air flowing through the heater core is not doing its job. 2- The heater core gets clogged up. 3- The valve to control amount of hot coolant flow to heater core gets stuck. Let's check if the water can flow to the heater core first, by disconnect the output hose from heater core while running the engine with heater set up at maximum level to see if coolant flowing out. Catch this coolant with a container to refill it back. This way you can eliminate # 2 and # 3. Good luck.
