My parents1.3 2000 fiesta with endura engine has a non working heater. The
blower works and all pipes get hot but no heat through the vents. There are
2 pipes going into the heater but which is flow and which is return, left or
right? Is there a bleed valve for air locks and if so where is it? Thanks in
advance.

Lee there is generally no valve. just the heater core is probably
clogged. you are right one is input and the other output. put your
hand on both hoses and see if one gets hot. that is the input from the
eng water. the other you need to disconnect if you can reach it if
those stupid car engineers didn't put it somewhere impossible to get
to, but I digress. and see if water is coming out of the pipe you
disconnect, if not hten your heater core is clogged and needs to be
replaced. If you are mx inclined its probably wise to get a book on
their car from local parts house. it will probably require taking the
dashboard out and steering wheel removal agin you can thank the stupid
car people for that I digress again.
