Question about Dodge Challenger
The heat just stopped working on my 2010 Dodge Challenger with 3.5l engine. I checked the heater control fuse and it appears to be fine. Turning the dial from cold to warm etc.. doesn't change the temperature at all. What could be the problem?
When you drive it a good long ways, do you hear the water boiling in the block when you stop? If so it's your thermostat.

Testimonial: "Thank you for your reply. I did not hear water boiling. The temperature gage also never goes above half way. Was doing research online and almost everything points in the direction of the thermostat. Bought a new unit for my car but it appears there is no way to replace it on my own. I am very handy if it comes to this but seems to be very difficult to reach. Couldn't find any actual info on how to replace it on my 2010 Challenger SE 3.5l. I guess the only way is to bring it to a dealer. I hate to pay $150 to $180 to install a $20 part."
Is your radiator fluid up where it should be? Low fluid will do this.

SOURCE: HEATER NOT HEATING
If your heater is not blowing warm air, your thermostat is probably sticking or your coolant level is critically low. When you start your vehicle, your radiator coolant begins warming up from being cycled through your engine block. One the cooland reaches a certain temperature (usually 130-150 degrees F.), your thermostat spring will retract and allow coolant to then pass into your heater core. However, if your coolant level gets too low, or if you are using a coolant mixture that has more water than antifreeze, thermostats have a tendency to rust and corrode and will stick. Thermostats can also go bad for what seems like no reason at all. The good thing is that usually thermostats are pretty easy to replace. It's the most common thing that would cause the problem that you're explaining. However, if changing the thermostat doesn't fix the issue, there is always the possibility that you could have a collapsed hose somewhere under your hood. If you change your thermostat and none of your hoses are in bad shape, you most likely will have a vacuum line to reconnect under the dash, as most heater controls in late model vehicles are vacuum operated. I'm almost positive that the thermostat will be your culprit though. **Make sure when installing the new thermostat that you use a new gasket or O-ring, whichever applies. Afterwards, start the vehicle and watch to see if you have any leaks around the thermostat housing and continue to observe until the temperature of the vehicle gets to normal operation temperature.
I hope this helps, and hopefully you'll have heat pumping through your vents in no time at all!
Have a great day and try to keep warm!

I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

it sounds more like the thermostat, a thermostat will cost around 8 to 12 dollars,just remove the thermostat housing and replace the old thermostat then reinstall the housing

Hi there, very common on these vehicles, you need to remove the heater cotrols and check that the cable hasn't come out, usually the clips that hold the cables in place break causing the heaters to not work properly, Nissan do modified clips now to stop it from happening, it may need a cable too if its too far bent, hope this helps.
