No heat in 91 cav

Need to check the coolant level to ensure that it is full. If full, check the hoses going to the heater core. Both hoses should be hot. If one is much colder than the other, you have a stopped up heater core. If that is fine, check to be sure the engine is getting as hot as it should. A stuck open thermostat will not allow the coolant to heat up enough and not blow hot air. If all that is good, check the blend door under the dash. It may be getting stuck in between the hot cold positions and not allowing all the air to flow over the heater core.

Depending on where you live, you could have a mouse nest in the fan motor, I haave seen this alot where I live, or simply could be a blown motor, have you checked the fuses?

No heat in 1997 ford taurus

couple things it could be something as simple as a pencil down the defroster blocking the blend door that seperates the condensor coils from the heater core it lets in varing amounts of air hot or cold depending temp setting. blend door is probably clicking if fan is running.make a hook out of a short piece of wire,coat hanger ,but only 8 or 10 inches long work it around through the floor vent opening . not a fish hook just a small circle bent 2 a 45 degree angle if u can bump the obstruction while switching hot 2 cold and floor 2 defrost it should work down and fall out the floor vent

We have a 2005 Grang prix and the heater will not but out much heat. We checked the coolent and it is full

Open the hood and with the heater running(be careful PLEASE), feel the lines going to the heater core(2 hoses running to the firewall, to the blower motor). Is one of them hot? If both are cool, your relay valve to allow coolant to the heater core is stuck. It will have to be replaced. Is the blower fan running( that's the fan in front of the firewall)? If the valve opens but no fan running, you will not get hardly any heat. If all that is working, You have a problem with the vent control valve(that will open the hose duct to allow heat to go through the vents). It works off of vacuum. A hose may have broken (they are made of rubber), or it may be just stuck. Check these first, before looking at the heater core. I hope this helps you

97 Ford Escort- no heat/ac/defrost or vent fan. Nothing will turn on. Checked all the fuses including the ones under the hood. Worked perfect one day then nothing the next. What could be the problem and...

OK the HVAC system has several components that make it work.
The actual heat is the hot coolany from your engine that flows though a heater core.
The blower fan operates on 12 volts, and runs through a resistor to apply your fan speeds.
The selector to run heat, defrost, ect. runs off of the vehicles engine vacuum, and opens and closes diverter doors.
The A/C uses a pump at the engine, a condersor coil and several switches.
I would look to the HVAC switch controler. Check for voltage there.
Please let me know.

The heater just up and quit working in my 1997 Jeep Grand Cherokee with no warning whatsoever. I can feel heat coming through the vents when going down the road, but the fan isn't working on any speed....

Does the fan work on A/C? If the fan isn't blowing, check the fuse. Heat when going down the road is simply an indication that the air from outside is coming through the system. If fuse is fine, blower motor is probably out.

1997 buick lesabre HEATER PROBLEMS The fan works fine but it doesn;t heat up. Cold air is always blowing out of the vents

This could be several things. First I would check that the thermostat is not stuck open. This will condition will make the car run cold when it is cold outside.

If this is not the case........and I'm assuming you've already checked that the antifreeze is full, make sure that the heater valve is working. If it is frozen in place then it won't move and won't allow the warm water to circulate through the heater core.

I'm basing my answers on a standard Lesabre. Yours may not have the standard climate control.
