If on a 1997 Jeep Wrangler hot air does not come out of the heater vents and the hose leading into heater coil is hot but the hose leading out is not what is going on?
Heater CORE, not coil. The core is plugged and needs back flushing or replacement.
Why would a 1998 Jeep Wrangler have a rust colored antifreeze continuing after a flush and a burning smell coming through the air vents?
How do you know which heater core you need to replace on a 94 ford aerostar front or rear you have heat but no defrost and stream comes out of the vents when heat is on?
Yes. The heater core provides the heat which blows out your vents. The heater core has engine coolant flowing through it (it is like a mini radiator) which creates the heat which warms the air that comes out your vents. If you have low coolant, there may be no coolant circulating through heater core, thus causing cold air to blow out vents.
Why do you get hot air at floor and defroster vents but only cold air at the dash vents vents in a 1995 chevyvan 20?
Why does heater defrost vent not open on a 1989 Sunbird and cold air blow from dash vents but no air blows from heater defrost vents and where are the enter and exit hoses for the heater coil?
I don't know why the vent would not open for the defrost, but it may be related to the fact that your heater core is blown. If your getting nothing but cold air out of the vents when the heat is on, your core is finished and if the core is finished then it is likely related to your vent not opening/switching. Something''s wrong with your heating either way.
I am assuming you are referring to the control for the heater that dictates where the air flow will come out? Floor, defrost, vents, etc? If so, there is a vaccuum controlled flap inside the heating system that controls that. I have the same problem with my 2002 Wrangler. Apparently, it is one hell of a job since it is buried and you literally have to take the whole dash of the car appart to…
The a-c on our 1998 dodge ram van sometimes blows through the dash vents and sometimes through the heater vents that blow on your feet What is the problem?
On a 98 Mystique the vent airheat will only come out of the defrost ducts- not the center vents or floor vents The Control Heater control switch is OK What should you look for?
Why does your 2003 Honda Accord heater blow cold air through the defroster vents and warm air through the dash vents?
Sounds like the thermostat is staying open all the time. Replace this first. This is the cheapest fix. Hope that works for you. If that doesn't work have the temperature switch looked at. They work off of vacuum. If there is a cracked vacum line it's not letting the door in the vents open and close.
