Question about 2000 Oldsmobile Intrigue
Hi, the most obvious cause of no heat coming through the heater vents is going to be that the thermostat has gone and will need replacing these are cheap to buy and not to hard to fit.
Now the other problem you could have would be with the heater controls the control that chooses hot or cold air may have packed up and may need replacing the best way of finding out it the thermostat has stuck shut is to feel the top and bottom of the rad when the engine is nearly up to temp dont burn yourself just give the rad a feel at the top and bottom and see if the heat is even all around the rad.
If you look at the two pipes going through the center of the bulk head towards the middle these two pipes go to your heater rad matrix now if only one of these is warm and the other cold then this means thermostat gone if how ever all the pipes are hot and the rad is hot all over then this would point to the heter controls being at fault.
Now if your heater controls are cable one of these may have broke and you would see this once you have the cover off the controls if how ever yours is electronic then the chances are you wont be able to tell if its working or not.
I myself would go with the thermostat first as this is the cheapest and easiest part to change.
Let me know how you get on or if you need further assistance ok

The blend door (mode door ) is a very common issue there is even an associated TSB t(technical service bulletin) it has to do with the blend door becoming warped and binding the accuator. In an opened or semi-closed position

The heat is generated by a radiator located in your dash using engine coolant. You don't have heat because the valve that is controlling the coolant flow is closed - either it or the commands that is controlling it are broken - find which and fix them.

My 05 sentra with 79k miles heat will warm up and then get cold after a mile of driving, we have tried to get the air pocket out, the mechanic stated he thought it could be a blown head gasket, another mechanic said it was a bad heater core. Any advice would be appreciated.

Ok, if you are trying to use your AC and its not turning on, odds are your refrigerant levels are low, the system will not turn on when low fluid levels are present so the system doesnt burn up the compressor.
If your blower motor is not operating, you may have a fuse blown that needs to be replaced, or the control chip that plugs into the blower motor (for fan speed settings) has burned up (easy fix).
If your climate control is not throwing out heat when you change the settings to hot, you have a leaky vaccume line and the vaccume pressure is not strong enough to open or close (depending on setting) your blender box. Although typically when a vaccume line springs a leak you will have issues with your selector switch as well (defrost, vent, floor)
Also pay attention to your temp gauge to make sure the thermostat is operating properly, and the engine is not over heating ro getting excessivly hot! If it is, then you need to replace the thermostat ($8 part)
and go from there. Also you should check your heater core, if it gets clogged or has restricted coolant flow, your system wont have the heat it normally did (if any) when it worked properly.
This is just a quick summery of the area's you should be looking into for the problems you are having! thanks for using Fixya.com and good luck, I hope I have helped make resolving your problem alittle easier

When I turn on the heat in my 2004 mazda mpv the front air vents blow heat but the rear air vents are blowing cold. I have adjusted every setting is there something I am overlooking.
