I have an 05 and when i wanna change it to defrost for colder weather i put the heat on but it automatically turn the a/c on (shows the green light on the button) and i've tried to turn it off but wont let me. I believe a few months back i was able to but is this normal? I'm sure i can tell it dies the engine down abit when thats on i haven't really notices if it is killin my gas mileage. If its not, how can i get this fix?

Thanks

Jeff

 

The A/C does indeed automatically come on with the activation of the defroster. It should, though, turn off when you press the A/C button once more. Take it in and have it looked at, unless someone else knows a quick fix on that.

 

No, it won't turn off on I think 03 and newer at all on defrost. There is a button mod you can do however that will allow you to turn it off like Ted stated.

Also, fwiw, air conditioning ≠ air cooling. It cools the air but it also pulls humidity out, so if you have it on hot, it will blow hot and dry the air out.

 

Nice job with the not-equal-to. Very impressive, Mr. Character Map user

To De-activate automatic a/c feature:

1) Turn vehicle off.
2) Turn fan knob off.
3) Turn temperature knob counter-clockwise to minimum (blue area).
4) Turn vent knob to panel only setting (next to max a/c).
5) Hold down both air recirculation button and a/c button while starting car.
6) Continue holding for 7-10 seconds until air recirculation button stops flashing.


To Re-activate automatic a/c feature in the future if you like too:

1) Turn vehicle off.
2) Turn fan knob off.
3) Turn temperature knob counter-clockwise to minimum (blue area).
4) Turn vent knob clockwise to defrost position.
5) Hold down both air recirculation button and a/c button while starting car.
6) Continue holding for 7-10 seconds until air recirculation button stops flashing.
7) After the 7-10 seconds described in step 6, the recirculation button will start to flash. Continue to hold the button for another 7-10 seconds. After this, the a/c light will turn to green and it's finished!

option+= ftw - know your keyboard!

Thanks for posting that - I was looking for it myself. The nice thing about this mod is that the a/c still kicks on, but now you have the option to turn off the a/c during defrost.

 

holy crap i just went to take a shower and 4 replys!!! Thanks alot guys I'll deactivate it. I usually try to figure it out myself but nope lol. Again Thanks

Now if I could just find the option key...
Start, Run, charmap. PC FTL on this one

This is a very handy mod along with the top down while rolling. I actually have been meaning to redo it myself since my dash wiring harness was replaced. Now I've got the info to take outside with me in a few minutes as well.

Right, Saki. It doesn't change the function of the defrost, just adds an ability to adjust it as desired.

 

Does this work with 2004+ AP2 ??

 

Couldn't tell you for sure, but the worst that happens if you try is it doesn't. Do a search at the BOTTOM of the S2000 Talk forum for Defrost Mod and you should get further info.

 

the activation of A/C is faster defroster anyways.. so the quicker it is the better so that you can see and then turn it off just as quickly so it won't waste more gas.
