hey guys im in ny and its cold my car isnt pumping out the heat i need to live like a normal american. if i leave my car running for some time with the air off i will get some heat when i turn it on but it dies down. the blowers work at level 1-3 4 doesnt work. it does blow warmer air but not warm enough. the level is topped off everything is good as far as that but what else can cause that.
I live in wisconsin and used to own a older 626 with the 2.0 8v efi engine. In winter, when it was really cold outside, the car never seemed to blow that much heat. It was like the poor little car and engine just was not able to overcome the bitter cold temps outside to make that much heat. The result of this was that there was not that much heat blowing out my vents in my car.
What you will see people do here in wisconsin in winter is they will block off part of the radiator with a piece of cardboard or something and this will allow the engine to build more heat and thus you get more heat inside the car too. You just need to keep an eye on your temperature gauge to make sure the engine isn't getting too hot. And also to remove the cardboard or whatever when it becomes warmer outside.
If you try this start by blocking say 1/4 of the radiator and if this doesn't help try 1/2 the radiator. I would think eventually you will find a point where you get better heat in the car and your engine temps stay within normal operating temps. Some people will actually attach something on the outside of the car where your openings are for the radiator. It looks kinda crappy but serves the same purpose.
If you've tried the other things like mentioned in this thread and nothing seems to work then this might just do the trick. Just keep an eye on your temp. gauge. Valvestem.
These cars produce plenty of heat, even in the bitter cold (at least after they're warmed up). When it's blowing cold air, what is the temp gauge in the cluster reading? If you're blowing cold air and the temp gauge is showing normal, most likely a heater core. If the temp gauge never reaches normal or is all over the place, thermostat is probably stuck open.
The not working on selection 4 is most likely the switch in the dash. If it were 1-3 not working, it would be the resistor pack behind the glove box.
