I do not know how to post so I am hoping that my request for assistance is picked up, as it is a very closely associated problem.

The heater blower on my Ford Festa is continually on hot, I cannot turn down, also have a leak from the footwell vents.

I have replaced the coolant valve, but this has not corrected the situation. I have been told that the problem is with the heater matrix, is this synposis / diagnosis correct. My car also has air conditioning which is a problem or added problem.

What would be the approximate cost for this part to be replaced and the air conditioning to be discharged and regased.

Also looking for the Radio cost on my vechicles radio M045774
