It only takes 3 things to get heat.
1: engine at 180F or more holdind, IS IT?
2: that coolant flowing through the heater core, (water valve open)
3: fan blowing air through said core. IS IT?

first see if your car has a water valve. 1/2 the cars have it others only
have an air damper.
so look for water valve, at the hose fire wall.
are both hoses hot , at near 180f? if not its blocked.
if both are hot, then the dampers is stuck closed.

I have a 99 grand am this summer i used the air conditioning, and very little cool air came out, alittle more when the car was going down the road. Now, it is cold outside the heat is doing the same thing....

Check to see if the intake for your heater core/ airconditioner is blocked. Its sometimes located on the passenger side of the car. Below the windshield. Sometimes there is kind of a grill below the window behind the hood. Make sure its not clogged full of leaves etc. You need outside airflow through that hole to go through your heater /airconditioner core to give you heat in winter, cool air in summer.

I have a 92 chrysler lebaron and there is very little heat coming from the heater. The engine is at operational Temp but no heat.

either the heat control valve isn't working, or the heater core is plugged up, what i do is reverse the heater hoses on the core to unplug the core sometimes that is all it takes but if its plugged badly you will need to replace it

2000 Honda odyssey little or no heat.

Sounds like a possible air lock. Trying running the vehicle without the rad cap until the rad fans turn on allowing the cooling system to burp out any air. Good luck.

Where to find the heated seat fuse and or circuit breaker

When you open up your fuse panel the back side of the cover has a list of what each of the fuses do. Sometimes it can be a little vague however , so if that happens its a simple thing to just pull them one by one and visually inspect them to see if they are blown. A blown fuse will have the little wire in the middle broken.
