I saw a few posts about heating issues, but no one seemed to pinpoint the issue I’m having with my cooper.
I am getting no heat at all from my cooper. I wanted to mention that when I put the heat on auto & HI or a high temperature the fans do not kick in. I can manually hit the “fan +” button and have it blow cold air. The AC is working.
I've checked the coolant level and it was barley under the “MIN” level. I filled it up to max and haven’t noticed any decrease in coolant for over a week with no heat still.
I've also checked all of my fuses listed below and they are all good.
There is no leakage in the cabin of the car near the heater core. The engine temp stays at half with no overheating. I don’t hear anything funny under the hood and don’t smell anything in the cab.
I think it might be a partially blocked heater core, but I wanted some second opinions.. thoughts?
If you remove the black plastic side panel cover (3 screws I think) to the heater box assembly down in the passenger footwell (on centre console side) behind you will find the flow and return pipes into the side of the heater matrix radiator (from the engine compartment)......are they both hot? In pipe/hose should be slightly hotter than the return and matrix rad should be hot.......there have been a few cases of a blocked matrix causing this problem here on Mini2. Lack of circulation flow meaning no heat, can also be caused by an airlock requiring bleeding of cooling system.
Thanks for the reply! I have not does this, and i will be able to probably tomorrow. I guess it should be noted that i did replace my coolant reservoir over the summer and did not bleed any coolant. Does this sound like it may be the issue?
If he has flushed and bleed the system correctly then the next thing to check is if hot water is getting to the heater matrix and circulating through it. Removing the plastic side panel should allow you to feel if there is heat at that point. Sometimes the heat is there but on switching the heater fan on it quickly cools due to lack of circulation in a partially blocked matrix.
Replacing the heater matrix is not a big job but can be a bit fiddly with hose clamps, etc and bleeding any air out afterwards.......there should be a couple of guides on Mini2 if you search.
