ok i dont know if this is normal or not.. but when i first get into my car i understand that everything will not work at full power until the car really warms up. but there are days when i have the heat on and i reach home and its still cold inside my car..... for instance. i have the automatic climate control.... i found that when i need AC i have to use to automatic feature because economy is like blowing warm air around.. so now when its cold out and i use auto and turn it up to 85 degress, the fans take a good minute to even turn on and then only one of them turns on.. i thought the point of the automatic feature was that it senses how cold the inside of the car is and adjusts... but when i use the economy mode for heat,, it also takes a while for the fans to turn on but it will get warmer over a long period of time......

but my main concern is why does it take so damn long for the heat to work properly.... maybe because i have leather?

 

... sorry.. i submitted that before i was done typing... but i think that maybe because i have leather and since the leather is cold it takes a while to feel like the heat is actually blowing hot air. does this happen to any of u guys with leather and auto climate?

 

What you should think about is adding one of those add-on heater turbochargers. Makes heating and cooling a synch.

 

Not to hog your thread but, what about if the heat you get is not hot enough, it still feels cool or luke warm. with the temp all the way up to 85. and the air circulation is set to interior mode. Engine is warm enough cause the needle is in the middle of the guage.

Does this have anything to do with putting freeon in ya AC system?

 

Maybe you need to change the coolant. I know when the car overheats the heater may blow cool air. I don't know, but its just a suggestion.

 

Mine dosn't take long at all, I have leather also...Maybe you need a new thetmostat.

 

Hold on boys and gals:

The way the auto climate control works is as follows:

Scenario: Its cold outside - you get in your car and press "Auto" and set the temp to 78.

1) The fans may not turn on immediately - this is normal - the auto climate control is trying to be smart and thinking I don't want to blow freezing cold air into the car yet.

2) So you start driving, as the car warms up, the fan-speed gets to 1-blade, 2-blade etc.. once the car warmed up sufficiently, the fan-speed will get to the max and your car will start warming up quickly. Once the inside temp reaches the set value, you will see the fan speeds drop back to a level that just maintains the set temp.

If the temp gauge (in your instrument cluster) shows that your car is at a operating temp (needle roughly in the middle of the guage) - and you set the temp to 85 and don't feel hot air coming out -then you have other problems - i.e. maybe blend door is not working or something related to the HVAC.

If the temp guage (after a 10 min drive or so) is not at operating temp - then you need to investigate the cooling system (most likely a stuck-open thermostat).

Oh btw, its got nothing to do with leather...

 

ok u just answered my question about why it takes so long for the fans to work.. i totally understand that now but i still have the issue about the air not being as warm as it could be.. it doesnt happen all the time but it does happen. one day the heat will be so hot i have to put the windows down and other days its like, why is there cool/luke warm air blowing even after 10-15 minutes of driving.

 

Oh btw, its got nothing to do with leather...

ya i knew u would think i was crazy for asking that but there is an obvious difference in warming/cooling times for cars with/without leather

 

oh another quick question, specifically for NJMODI - can u explain the difference between economical and auto. obviously i understand the major difference but i mean as far as how they work. because i get a lot more output out of economical than auto when i use heat...... but i do understand the difference between the 2 when i use the AC

 

I don't remember all the differences - but I know that no matter whether you are running in "AC" mode - where the car temp is lower than the ambient temp or in "HEAT" mode, where the car temp is higher than the ambient temp, the compressor does not run at all in ECON mode. I think the differences are outlined in the car manual.

I don't know anything about how auto or any HVAC systems actually work - so I can't help you with why the air is warmer in ECON mode over AUTO mode.

 

well thanks for the help. my car didnt come with the manual... i downloaded it somewhere but lost it.....

 

You Probaly Need A Thermostat. Cabin Heat Comes From Hot Engine Coolant Pumping Through Your Heatre Core. The Fan Blows Over The Heater Core And Turns The Air Warm. If The Thermostat Sticks Open The Coolant Takes A While To Heat Up. The Thermostat Is Closed Until The Coolant In The Cylinder Heads Reaches About 180 Degrees. Then It Opens And Heats Up The Rest Of The Coolant In The System. This Is A Very Basic Explanation But Check Your Engine Temperature Needle On Your Dash. If It Takes A While To Start To Move Then You Need A Thermostat. If Not Then You May Have A Mode Door Problem, A Vaccuum Problem, An Electrical Problem Or A Clogged Heater Core.

 

econ=no ac at all and therefore is good for windows open or in winter but in winter it will fog up ur windows as theres nothing to dry out air (ac compresser does this)
auto=ac works i believe only when it needs to use this most of the time but not with windows open or when racing =)

 

njmodi might be right bout the blend door, it might be stuck partially open giving only warm air. the differnece between economy and auto is that economy doenst make use of teh compressor, notice that when you press the defogger button for the front windshield, the climate control kicks into "auto", meaning the AC compressor kicks on, it has the same effect as turning ont he AC and having it blow at the windshield, try te same thing with economy and it wont defog the windshield at all. i only use auto in the winter time when i need to get rid fo the condensation, after its gone i kick it back into economy.
