So I am in quite a pickle. I am currently flushing the coolant from my 2.4 L 2013 Dodge Journey SE and I decided to replace the thermostats while I was at it. Before I did replace them, I decided to take them out and reinstall the thermostat housing so that when I flushed with coolant cleaner and water, it would go through the engine as well without being stopped by those thermostats. When I went to go to to turn on the car and put the heater on HIGH at full fan so that the water pump would turn on to circulate the cleaner, I noticed that no air was coming out of my Dashboard. Only through the Defrost vents and Feet vents. I tried waiting to see if it would get warm but it didn't as well. I think I might have done something wrong when taking out the thermostats but I have no idea what it could be? All I know is that when I turn the engine off I hear two or three clicking noises as its shutting off. Can anyone help me?
