JK Heat not working

2010 with almost no mileage has no heat anymore. The fan is working well but when i engage the thermostat to the heat zone i only get cold air.

Can anyone help me figure out what's wrong ?

And is it difficult to get the heating element behind the dash ?

Thanks in advance

H.

Check your antifreeze fluid level. I had a similar problem and added more fluid and the heat worked again.

could be a blocked heater coil.


I had my 2014 Sahara radiator flushed...they removed a ton of sand.


If sand is in the heater coil, its bad.



Sand left over from casting the block was a problem on earlier JK's
