SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

SOURCE: location of the heater control valve

There are 2 hoses going through the firewall from the engine, these are the coolant hoses to the heater core, one is 3/4" and one 5/8", the control valve should be in the larger line (3/4") which is the inlet, make sure that the valve has vacuum (heater on low), also check and see if both hoses get hot with the heater blower on low, if they do get hot your problem is not the heater control valve but the air temp control blend door actuator.

SOURCE: where is the heater blower motor resistor located

It is located right next to the blower motor because it stays cool with the air from the blower and I think it has a 4 wire connector depending on how many speeds there is on the control.

SOURCE: 1997 Jeep Cherokee - Blower motor stopped working.

Check the relevant fuses with a test-light or VOM, don't just "eyeball" them as they often break at the very end. Then check the heater/A/C relays on the electrical panel. The heat/cool is controlled by a stepper motor which opens and closes the air "mixing box", but it won't work with a bad relay. If all of those check-out, you need a OBDII code reader to check the "engine" computer, as it controls the electrical modules. Also check the fusable links going to the electrical panel, and the cable from the battery to the panel. The cable may be corroded in-two and you'll never see it, so no juice to the panel, no juice to the heat/AC system. (I had a Dakota do that.) PS: Double check the grounds that they aren't corroded. Learned about that from a BSA Gold Star production racer.....

So you're getting heat but no blower to circulate the heat, right? It's also possible the fuze is blown to the blower motor, the switch that adjusts the speed of the motor could be damaged, or its resistors that limit voltage, to control speed could be "open" (burned up). I would check many of those before replacing the fan..

The heat is controlled by a valve that allows water to circulate through the heater core. If the fan is blowing cold air, check the valve, or blow water back and forth through the heater core to clean it out.

2000 mitsubishi mirage. cannot get no heat. changed heater core/thermostat/water pump/ heater hoses still want get hot


Is the blower fan working? If so, Is the heater control valve(valve that allows coolant to to to the heater) working? Its electronic and has been known to fail. Its located at the base of the heater hose and has a couple of wires attached to it. If that is bad, you can get one at the auto parts store, and replace it yourself. Hope this helps.

My 94 gmc sierra has no heat, new heater core and blower works, also has new termostat...any suggestions?


You Might want to Check your Heater Control Valve,Its located under your Hood between 1 Heater Hose and your Water Pump.Its Vacum Operated and could be manual as well.Have someone turn your heat on and Off while you watch under the Hood at the Heater Control Valve to See if you see it Move.Or could have a Leak.More than Likely its Frozen Closed not allowing the Hot Water to Run Through Your Heater ore ,Which Results in No HOT AIR blowing inside. Try This 1st.

No heat


your blower motor resistor needs to be replaced if you only have one speed its a small inexpensive part runs about 15 dollars easy to replace.

Heater blows cool air instead of warm air


check your coolant level if it is low top it off. if it is full you may need to change your thermostat to get the temp back to normal. for the heat check the heater control valve to make sure it isn't stuck (heater control valve should be located against fire wall connected to heater hose.

The heater quit working in my 2003 dakota 3.9 liter v6. A liitle heat comes out, but not much even with the gauge turned on high. Fuses in truck look good, coolant level good. Where is the location of the...


The control valve could be damaged or you could have a blockage in the heater core. Locate the valve in the engine compartment and watch it while someone inside the truck moves the heater lever back and forth. You want to verify that the valve is moving to open and close the pipe into the heater core. If that checks out ok, try to flush the heater core.

No heat, heater core is good,blower moter works


Check the operation of the heater control valve. If it doesn't open up no heat. If the cable moves the control on the valve take the valve off and check it manually. The lever may work but the valve still doesn't open.

No heat,ch.thermostat,water is circulating,blower goin strong .


Check the 'heater control valve'. This valve opens when u turn on the heat switch on the dash, so the hot coolant will flow thru the heater core and provide heat. So although the coolant is circulating in the engine, the valve controlling the flow to the heater core is stuck closed, or not working.
