Heater not working

I was warming the car and turned on the Heat/Defrost expecting to defrost the wind shield but only cold air came out.I hope this is a very easy fix?

Thanks for the tip. I was doing some research on my own and your answer was a repair that was recommended;also I was told to check my anti-freeze ratio in the radiator. I put a little more water than anti-freeze because my small radiator hose found a hole in it so my anti-freeze was about a third of a bottle so I put in more H2/O. So I will be flushing out that mixture and put in some good anti-freeze to see if that will fix the problem as well. Thanks again caradiodoc

I will try what you suggested, Thanks again.

This is my "baby" in question!

Heater problem
1997 Subaru Legacy 4 cyl All Wheel Drive Automatic 190, 00 miles

The defroster and heater does not work. Are there any fuses that would control this, or is this a problem with the thermostat? The temperature guage in the car is always in the normal range.

Thanks for getting back to me. My husband figured out the problem. A little door behind the glove box had a small cable attached to it. The cable had come off, so the door would not open. All is well now and plenty of heat.
Thanks anyway. I will use you again if need be.

Engine Cooling problem
1991 Subaru Legacy 4 cyl All Wheel Drive Manual 198800 miles

My 1991 subaru is overheating and I have no heat.
Have changed thermostat and water pump but it still overheats and still no heat.

Engine Cooling problem

I've tried to drive home from college only to have my car's thermometer to red line about 5 miles off campus. I've replaced the thermostat myself and flushed the coolant system. Still have no heat and over heating. I've noticed even when red-lined the radiator is blowing cold air and I am not seeing any leaks in the water pump. There is no "ice cream" seen in the oil cap that would indicate that there is no blown head gasket. I have had a coolant leak problem but I have been unable to locate that leak. As far as I can tell its not near the water pump and might be one of the connecting hoses on the bottom of the coolant tank. Some have suggested the water pump is malfunctioning, are there any ways I can test this or something that I should look for. Could it be another problem?

PS the car isn't worth more than $1000, so I'm trying to avoid costly repairs. But I do need it to get home.

The thermostat I bought from the auto part store was faulty, and had to be returned, the car worked fine after the thermostat was replaced (again)

Engine Cooling problem
1995 Subaru Legacy 4 cyl All Wheel Drive Automatic

i just changed the lower radiator hose and flushed out the radiator in my 95 subaru legacy and now I have no heat what did I do wrong?

It would seem to me that there is an air pocket in the cooling system that needs to be bled out.

Overheating and putting out no heat from heater. I have replaced waterpump, thermastat, radiator and hoses with new ones. Waterpump is turning good with belt and engine runs great. Takes a long time to overheat with no leaks. Never produces any heat from heater.

Open valve and back flush it to clear crud?
