Thats a vacuum leak. The vacuum lines (7/32" and 5/64?") dry rot after a few years. There is a "vacuum storage" ball, either on the hood, behind the Driver's side hood hinge or behind the fender, depending on your model. The vacuum for this and the controls comes from a "t" off of the PCV check valve. Find the ball and check the hoses.

My defrost fan is blowing but will not defrost my windows?
That means either you have air in your heater core or your heater core is being bypassed
Blazer ac is blowing out hot air?
It may have a bad heater core.
1989 Chevy Corsica has no heat or defrost or blowing at all why?
If you feel no air blowing at all (when you are not moving) then your fan is not blowing. If it is blowing air, and it is cold, when the heater is on, then most probably your heater core is leaking, or is clogged. These are easily replaceable and go bad all the time in older cars.
Why would hot air come out of the defroster and vent work but not the heater on 95 S10 blazer?
What causes heat to only come out of the defrost and vent but not the floor of a 1995 S10 Blazer?
Why do you keep blowing fuses when you turn on the heater fan but when you take out the compressor fuse it doesnt blow the fuses?
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
What could be wrong is a 1997 Chevrolet Blazer when there is little heat blowing?
Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
Why would the fuses for the heater keep blowing in a 1985 Blazer?
Beause there is probably a short/bad connection in the switch, or the blower motor itself
The heat and front defrost stoped blowing hot air on your 1997 Nissan Altima The ac works fine Could this be the thermostat or is it the heater core?
check the antifreeze
Car heater just defrost work?
When you set the control, if you chose defrost, it usually does it at the temperature you specify. So if you want heat only blowing through the windshield vents, which I believe may be the question you are asking, it varies between makes of cars. This is what to look for : defrost, fan speed, temperature. If you mean "Can a car that only has a heater ( no air conditioning ) be used to defrost?" The answer is still yes. I believe the question is missing words. It is comparable to asking "Hand, just finger work?" You might try asking again, being more specific, explaining why it is a problem.
Your ac heater and defrost in your 2000 montero stop working when a fuse was replaced it kept blowing the fuse what is the problem?
either the fuse that was put has too much wattage or not enough
How would the repair of the heater and air conditioning not blowing be made on a 1994 acura integra?
I own a 1994 acura integra and the heater/air conditioning blower is not working, I can not defrost my windows and the heat does not blow. What is wrong and how can the problem be fixed.
I recently bought a 1992 Grand Prix and the heater died but the rear defrost still works Any suggestions?
The rear defrost is electric. The heater works off the hot water in your radiator running thru it and a fan blowing the heat into your compartment.. check your thermostat, it could be that your heater core isn't getting and water to it, that is were your car get's it't heat from, if not that it could be lack of water
