This also happenned on my Liberty. It was not in the switch or in the fuse box, a part needed to be replaced by the dealership.
Addendum: That might have been the fan speed resistor block that they replaced.
Ninety-eight per cent chance that was the fan speed resistor. I bought one on eBay for $27 and replaced it in about 10 minutes. You need to drop the glove box by pushing in the holder clips. Inside you'll see a part with several wires held to the heater housing by two bolts. Remove the bolts, turn around the assembly, and there's your resistor, ready for replacment. Piece of cake.
heater resister is bad
There are signs that there is a problem with a hot water heater. When you cannot get your water to heat. It could be signs that the pipes leading to the heater are leaking. It could be a problem with the thermostat in the heater.
I just had that same problem..I took it in to have it fixed and they replaced the blower motor resistor and that seems to have fixed the problem
if the heater does not blow out warm air change the setting.
how hard is it to replace the heater core in a jeep liberty limated editon step by step instructions
vent door will be open to what ever setting u set it on regardless of what temperature setting you are using
The thermostat setting on the water heater controls the temp.
your fuse is messed up. we just had the problem replaced it and we are good to go. its about $7.00
Heater is not working in a 2002 ford foucs only work when fan setting is place in?
Take it to a repair shop
Not enough info. Car heater? House heater? Gas? electric? Water?
If the blower is good then the problem is coolant. Something is stopping the warm coolant from the engine from reaching the heater core inside the car. This might be thermostat, heater control valve, blocked heater hose or a blocked heater core. I would suggest letting the car warm up and checking the heater hoses (2) by hand to see where the hot water stops. If there is no hot water at all it is probably a thermostat problem.
if it is magnetic, use a magnet tied to a string or something if it isn't magnetic, then take off the cover and reach in if you can't do any of those, that is a problem. if it is flamible, don't use the heater. if you arn't sure, don't use the heater. taking apart the system would be another option, but that isn't very cheap if you can't do it yourself. if none of those work, call the company that made the heater and explain the problem.
was there something on your dash that fell in the vent, a bad fan will make noise all the time.
No, that is where you put it to light the pilot light. That is the only thing that will come on at that setting.
The thermostat is probably stuck in the open position.
that has a lot to do with.if your heater core is pluged up you wont get any heat out of it.
Your heater fan resistor module requires replacment
Have you turned the control from Pilot to On? Have you increased the temperature setting?
Answerheater core will most likely be the problem Answerheater core will most likely be the problem Had same problem. Is your temp gauge reading normal? If temp gauge is reading low after driving awhile, may be the thermostat stuck open. If so, easier fix than heater coil.
You have to replace the thermostat it is stuck open. I would say. Do you have heat when you are driving? I Have the same problem and is trying to fine where it is located. It is usually at the top of the of the motor but not on my 2005 jeep.
Whats the problem? Blows cold air with the heat settings on?
