couple of questions on F430

1. not sure anyone actually knows the answer to this. to get the air to stop blowing i press the re-circulation button

 

With the on/ off pressed in, you should get no airflow. When it is out you get air flow

All 430 has pre cats in the manifolds which have a habit of getting sucked back into the engine

 

1. You do not get heat with the a/c switch in the off position. It will blow ambient air in the off position. It must be in the on position to get heat in the winter/cold in summer depending on the temperature setting.

 

Glad I'm not the only one confused by this. I thought it also depended on if either than temperature control or fan control were set to "Auto". User manual doesn't help. And before you ask, yes, both directional arrows blink whether you have your left or right turn signal on.

 

I agree quite confusing; the old hit the buttons and try different combinations on the control tends to work in getting the hot air out; usually.

 

This same thing comes up every couple of months. It is climate control; it is not hot/cold. If you think about it being climate control on/off it makes perfect sense.

 

with climate control off air still comes through the vents - thats what i understood the OP question to be. to get no air from the vents you need to have the system off and push the recirculation button

 

TT you are correct. And turn the fan off.

 

What happens if u press the recirculation button like i said?

Yeh i dont get it. U cant moderate with the temperature control? Good luck

Not sure. I really only drive my 360 cs and 430 in summer so i usually have ac on or system off and the top down.

To be honest im confused myself now. I thought u were originally asking how to stop air flowing from the vents

I throught i used to understand the system, now u r getting me confused.

 

Not a 430, just a 360. One thing I do have, is if I don't actually use the air conditioner in my Modena, there's a very faint warm flow of air that comes from the vents. This assumes I have not placed it on recirculating air, and it is not also turned 'off' with that one button. Once I turn the air flow dial to auto or to 1, 2 or 3, then, and only then will it begin to run cool air if I chose a temperature which is supposed to be cool, rather than warm. I'm thinking it might have been easier to just keep it always warm via the radiators giving it some heat unless the owner explicitly decides to choose a cooler temperature, after which the condenser turns on, and there's always just a little bit of warm ear leakage due to the design if the driver chooses not to. I may be very wrong with my thinking, it doesn't really bother me...

 

im asking jerry to opine - he knows everything

 

Thanks for the compliment Ricky. In this case Im confused too! The only thing I can add, most modern cars, and I think the F430 also, monitors the outside temp vs the inside temp and so if you select 70F for your desired interior temp and if it is 32F outside, it will run heat. If you select the same 70F and it is 90F outside, then it will go for AC. The F430 HVAC would require periodic adjustment while I drove- the longer I drive I would have to just nudge the temp one way or another. I think you are operating it correctly. So I suspect something is wrong with your cars HVAC.

 

Yes, according to the 430 manual, that's how it should work. The ON/OFF only controls the AC and should have no effect on the heating function.

The 360 manual says the same thing. I am not sure why your CS is behaving differently, but I do know there is enough variation in behavior based on model year and specific car configurations to cause confusion.

 

I think the 328 is so much simpler. You get hot air no matter what, even with the A/C set to max. But with the A/C on, at least you get a splash of cold water on your wife / girlfriend / navigator / codriver’s feet in the middle of every left hand turn.
