If it does, then check the operation of the valve, situated on the side of the heater matrix. The heater matrix is in the centre of the vehicle, under the dash. Roughly behind where most car stereos are situated. You'll have to remove any black, plastic shrouds to get to it. Work the hot/cold setting and check the valve for movement. If it is a motor actuated valve and in the even the valve doesn't move, then also check power to the motor. If you have no power to the motor, or if the cable operated valve isn't moving then check the switch mechanism or wire/wiring.
try replacing thermostat and do a coolant flush, heater matrix behind dash is prone to blockage or leakeage ( with leakage usually footwells are always damp ) before you replace the coolant after flush, fill and drain with water a couple of times, should sort it and it easier than replacing heater matrix. if heater has not been working for a while, as in 12 / 18 months matrix replacement might be only option, but spending a couple of quid on flush is worth a try first
the mechanic is right however if the heater matris is broken or cracked putting a epoxy steel putty would do the job for a while but not for long. secondly, ask the mechanic if it is possible to put a new pipe or high temperature hose similar to radiator hose material and if he could instal it if the hose is also broken.
FYI: your heater matrix uses your engine coolant to heat up the matrix so it's just one of those solution could solve the problem rather than junk the car.
This can be an outcome of a Faulty Heater Matrix. Try flushing the Heater Matrix. Try also looking at the Heater Valve. They are very vulnerable to be jammed or blocked. Try replacing by the help of a certified technician of Ford.
Thank you Sir, Have a nice day.
