Car Forum / Ford / Ford Focus / August 2006Hot air from ventilation openings
Although I put heating on cold/blue relatively lukewarm/hot air flows from ventilation openings ... I have noticed that there is one very hot box situated in the center and down from ventilation control in direction to the pedals behind plastic air openings. Car is Focus year 2000 without air conditioning I bought it few days ago so I don't know if this is normal for Focus or there is again some fault on heating radiator. Heating radiator was repleaced few months ago because of leaking. Old owner gave me papers from Ford dealer. Can I do anything about this? Maybe some cold/hot water valveor something like that is not mounted properly? Or? Thanks. Also if anyone can comment what should I take most care of on this car good bad sides etc... I have a 2001 with a/c and when the a/c isn't on I get the same thing. > Although I put heating on cold/blue relatively lukewarm/hot air flows from > ventilation openings ...

Sounds interesting, just tested this with a small LCD thermometer putting the outside sensor (cable) directly into one of the center vents, but can't really acknowledge it. There was no real difference shown to my outside thermometer (1999 wagon). For the fun of it turned A/C on to measure and quickly temp dropped down to 1/1.8 C/F, much more then expected. ;-)  SignatureMichael Heiming (X-PGP-Sig > GPG-Key ID: EDD27B94) mail: echo zvpunry@urvzvat.qr | perl -pe 'y/a-z/n-za-m/' > In alt.autos.ford.focus Tim.. <the.farm.hates.spam@btinternet.com>: > [quoted text clipped - 14 lines] > For the fun of it turned A/C on to measure and quickly temp > dropped down to 1/1.8 C/F, much more then expected. ;-) Please can you check if heating radiator under the vent. control almost on the floor of the car is warm when heating is off.

I know it comes in from below the windshield, but does that come Thruogh the egine compartment? or just over the hood, which could still pick up some heat. Micheal, your AC cooled it to 1 degree C? thats almost freexing, I haven't had an AC do that since I had a freon one in my '86? Tempo, that would put out about -2C / 29F with recirculate on. >> In alt.autos.ford.focus Tim.. <the.farm.hates.spam@btinternet.com>: >> [quoted text clipped - 19 lines] > Thruogh the egine compartment? or just over the hood, which could still > pick up some heat. I checked it again it seems thet problem is in cabin radiator which is really hot when heating is turned off... Are there any hot water valve or something similar?

The problem might be the heat exchanger as "Dudo" pointed out, haven't checked about the Focus, but any other Ford owned by me had some kind of cover you moved with the temp control over the heat exchanger. There weren't any valves to control refrigerant flow manually. From the beginning of my test it was turned complete to cold air. Perhaps you have to drive longer (30 min.) to measure the difference? Did took a look today, but things are quite compact and I wasn't able to find the heat exchanger in second today. > Micheal, your AC cooled it to 1 degree C? > thats almost freexing, I haven't had an AC do that > since I had a freon one in my '86? Tempo, that would put out > about -2C / 29F with recirculate on. Indeed found the cooling capacity quite respectable, though it was just 24C outside. But even with outside well >35/95 C/F you have to turn it off frequently even at low fan speed or you'll freeze to death quite soon... Ops forgot to test with recirculate on at all.

In that case this could be big design flaw on ford focus if you wan't to drive it comfortably in hot climates like summers in Croatia are without AC. Actally heat exchanger is allways hot in my car (you can't hold finger on it because of temp.) so it seems if everything is as you wrote that we allways have source of heat (cca. 90-100 degrees C) in the car?

I'm guessing you mean *coolant* flow? As far as I know, Ford and many others have not used a valve on the heating system since the 1960's. It is not a design flaw; there are a number of advantages in this approach. A flap is used when the temperature is set to the coolest setting to prevent air passing through the heat exchanger. It may be that yours is broken or out of adjustment because I have never noticed unwanted hot air coming in to the car in the seven years I've owned my Focus. If there is a weakness with the Focus heating/ventilating system it is quite the opposite. There is insufficient air flow through the car, so it tends to mist up quite easily. Also, in the coldest weather the heater is barely adequate. HTH Chris SignatureRemove prejudice to reply.

This is my experience with Ford, though I haven't checked on my Focus. Ford uses just the usual thermostat to separate the radiator, from the circuit if the engine is cold. > It is not a design flaw; there are a number of advantages in this approach. > A flap is used when the temperature is set to the coolest setting to prevent > air passing through the heat exchanger.

This might be well the reason or simply some dust/dirt preventing to close the flap completely? IMHO vents are much more likely to break then this simple technology. > If there is a weakness with the Focus heating/ventilating system it is quite > the opposite.

Found the heating quite sufficient, though it takes a little time especially with the wagon if it is really cold. Indeed, some rain and the Focus fogs up quite fast, even if I have exchanged a few parts recommended by Ford (TSI - technical service information), it got a little better but still annoying, the only thing you can do is turn on heated windscreen and turn on A/C to get a clear view back...Unluckily it rains quite often in my area...;( Don't suppose the reason due to a wrong mounted interior air filter as some pointed out, as all service has been done by an official Ford dealer. Though I could double check of course, but there would be no TSI information and some fix in production if there wouldn't be a problem.

I don't know about winter but during summer heating radiator with hot engine water/coolant at 90-100 degrees C is simply one unwanted source of heat in the cabin.... at least when gets hot and the car doesn't have AC > Indeed, some rain and the Focus fogs up quite fast, even if I > have exchanged a few parts recommended by Ford (TSI - technical [quoted text clipped - 8 lines] > there would be no TSI information and some fix in production if > there wouldn't be a problem.

From your other contributions it sounds like someone has worked on the heating system of your car and perhaps left it in a state you suffer from? >> Indeed, some rain and the Focus fogs up quite fast, even if I >> have exchanged a few parts recommended by Ford (TSI - technical >> service information), it got a little better but still annoying, >> the only thing you can do is turn on heated windscreen and turn >> on A/C to get a clear view back...Unluckily it rains quite often >> in my area...;( >> Don't suppose the reason due to a wrong mounted interior air >> filter as some pointed out, as all service has been done by an >> official Ford dealer.

Have never checked about mine, it doesn't happen any time it rains and I can control it with the heated windscreen and/or A/C quickly, though it shouldn't happen in the first place.

Yes they changed cabin radiator because of leaking... few months ago...probably they didn't do something as they should and hot air gets in.... and btw. air recirculation switch works randomly... One day it works another day don't...

Well then maybe is something broken or out of adjustement with that flap in my focus because ventilation canals get really warm and when temp outside reaches 20-25-30 C it simply gets too hot in the car... Please if you have any documentation how to disassemble ventilation system could you sand me it on my email... Btw. that 'heating radiator' was changed few months ago at least old owner said so...maybe they didn't assemble it correctly... > If there is a weakness with the Focus heating/ventilating system it is > quite > the opposite.

Well I have this car for one week only so have to get a bit colder to check that... :-) [..] > Well then maybe is something broken or out of adjustement with that flap > in my focus because ventilation canals get really warm and when temp > outside reaches 20-25-30 C it simply gets too hot in the car... There is something wrong with your car then, without a doubt. > Please if you have any documentation how to disassemble ventilation system > could you sand me it on my email... > > Btw. that 'heating radiator' was changed few months ago at least old owner > said so...maybe they didn't assemble it correctly... I don't think that's a "maybe"... Can you find out where the last owner took it for the repair? Then perhaps you could return it to them to do the job properly.
