Heater doesnt work but ac does

Assuming the fan blows OK but you have no heat. Go to the firewall and notice where the heater hoses enter and exit the cabin. You'll notice a metal manifold and also a rubber bypass hose that connects the two. This bypass hose is a design problem and causes the coolant to bypass the heater core which is located inside the cabin under the dash. Over time, the heater core gets blocked by gunk and you'll get no heat. All the coolant flows through the bypass hose when this happens. The fix is to flush the heater core itself. It's difficult to access at the firewall, so I disconnect the two hoses at the engine itself and attach a garden hose to flush it. Before doing this you must clamp (vice grips) the bypass hose so that all of the water goes through the heater core.

Need to know how to bypass my heater core for the summer

Take the heater hoses off the heater core at the firewall and join them together with a barbed fitting and a couple of hose clamps. That will do it...Mike

No heat in 99 taurus.....bypass line is hot, but lines to heater core are just warm. if i pinch bypass hose i get this a bad thing to do?

I had the exact problem with mine and had to replace the heater core and that was the problem. same exact symptoms. also make sure that you have a good system flush done or do yourself but make sure the whole system is flushed well and through bottom drain. these cars have a issue with clogged radiators which will lead to many more issues if not checked. good luck!

I need instructions on how to bypass a hearter core in a 98 grand am GT. 3.1L

Connect the hoses that go to the firewall-this will bypass the core until you can replace it and can be done with a 5/8" pipe and a couple of clanps.

How would u direct airflow over another heater core to the passenger compartment?
no u must remove the entire dash to replace the heater core, there is no other way to get heat into the car.

Why bypass the heater core? whats the out ***

there are pretty much two reasons someone would bypass the core 1. it is leaking and for some reason they don't want to or can't change it now. or
2. there is a heater control that can't be easily reached that is causing hot air to blow into the cabin in the summer. (there are other ways of fixing that though).
Either way, in bypassing it, the flow in the cooling system is not interrupted and it does not cause any damage to the engine. (where blocking it possibly could, even though that's unlikely)

No heat in 2000 chevy lazer just replaced thermostat

I own a 200 Chevrolet Blazer and I have it for over 4 years mine does the same thing I actually just noticed my heat getting less. My husband found the best way to fix it and the cheapest way to fix it. He takes the tube off the heater and attaches a water hose to it and flushes out the gunk whatever is blocking the hose and after he does that the heat works great. No cost and if I wanted to I could do it because its so easy. My husband did some searching on the internet and a person that this happens all the time to let me husband know. If you need more info let me know I can ask my husband he isn't home at the moment I so I don't have exact details. Thanks Amy
