93 Ford Mustang Lx 4-cyl ... no heat.

Live in Minnesota and no heat out of heater or defrosts is a problem...

The heat gauge does not rise above 130 or so.
So, I thought it was a thermostat, car is new to me.
But, under the hood the engine seems warm, hoses are warm after running it but not even a hint of heat...???

Could the heater core be plugged?
Looked at the hoses going into the heater on fire-wall and they are the old type connections and hoses are warm. ?

What to do now?
Thanks in advance for help.. MJohn

Warm Saturday here so I decided to take another look.

removed the electrical part in the upper heater hose and replaced it with a deep 9/16" socket. Still no useable heat?

still searching for the answer to this problem...please help. ?

Is the blend door opening? Is the thermostat closing, allowing the motor to operate at high enough temperature? Is the coolant system full? Does the car have an electric radiator fan, and is it turning on and off when it should?

blend door ... is this under the dash?
thermostat closing?
I did get some heat with the air conditioning on max.
blower seems to blow good...

Can't tell if the temp gauge is connected as it does not rise far about the 130 area on the gauge.

The blend door is located under the dash.
If the thermostat in cooling system is not closing, your motor will not run hot enough to put out much heat. Also you may get poor fuel mileage.
