Is there a heater relay switch/fuse
The blend doors inside the system are what makes the heat ac work there are vacuume motors going to each door if the vacuume lines are cracked or broke the doors wont work and they can sometimes stick

yes blower fan works, I believe I have found the problem one of the lines to the heater core appears blocked, because one line is cold to touch and the other is hot I will attempt to flush these lines later today to see if I have solved the problem
heater coil hoses going in and out are hot ......still have cool air
I get heat for about 30 seconds and then I get nothing but COLD air.
99 taurus, no heat. Reading posts & ended up changing water pump, NO HELP. Flushed heater core - instant heat - relief - for about 2 months.
Seems system is clogged beyond simple flush. WIll repeat flush. Read another post that said multiple stop/start hose flush because stuff stirs up, settles and repeats.
Does the blower fan work?
I have a 1999 Ford Taurus and the Power window Switch does not work How can I replace it
