Hey guys so on wednesday i went to six flags and down the shore and coming back home the ac stopped working and so i turned my car off and the ac starts to work like the fans turn on and then they stop after like 5 seconds. whats the issue? thanks

ezone

Does the inside blower fan work or not?

Rahway09

you feel the air for a quick second and then it stops

ezone

Does that mean the fan doesn't work?


If the blower fan doesn't work, the HVAC controller shuts down the AC system.

Rahway09

lol sorry im a noob how would i know if it works or not? and what does it mean if it shuts it off? easy fix or no?

anibis

Does the air stop coming out of the vents? Or is warm air coming out?

Rahway09

you feel cold air for like a second and then it stops coming out of the vents and the fans stop!

Not an a/c problem then its your blower motor..

Rahway09

ezone= lol sorry i need to learn more about cars lol

04 honda civic = is it an easy fix ?

ezone

Had nothing to do with cars.

I thought it was a pretty simple question: Does the fan work, or not? The fact that it is inside a car has nothing to do with not being able to answer the question.

If you were sitting in the Lazy Boy Recliner, in front of a box fan in your apartment, with your eyes closed...how would you know if the fan was working or not?
You can't SEE it spinning.
You can't SEE the air moving.
What would your clue(s) be?
Feel? Sound? What?

Now you are sitting in the drivers seat. Same scenario.



Depends on WHY it isn't working.
Power?
Ground?
Power transistor?
Fan motor?
HVAC control unit?
Garbage caught in it?


Test.

Lol well when i turn the ac **** to on i hear the fan start up and it sounds like its gonna work and then if u put ur hand on the vent u can feel it quickly but then the fans stop. somebody told me that maybe im out of freon but idk i just want to get it fixed cuz its been so hot outside it sucks to have the window open lol

ezone

That CANNOT stop the inside fan from working.
Ignore this person for the moment.

Which fans?
The one fan inside the car, or the two fanS outside the car?


I think it will be much faster and easier if you just take it to someone that knows what they are doing, and pay them.

Rahway09

ezone=lol yea and all the fans stop working cuz i opened the hood and turned the ac on and the two fans stopped plus the inside one blows for like a second and then stops as well and yea i think so too lol how much would u expect to pay for this ?

ezone

The inside fan MUST be fixed FIRST.




No idea what is broken yet.


See if you can find a procedure for doing the self test on the a/c control panel, that might give more clues.
I didn't find one right away, my google-fu is weak.

Climate Control
General Troubleshooting Information 21-104


How to Retrieve a DTC

The Climate Control Unit has a self-diagnosis function.

Running the Self-diagnosis Function

Turn the fan switch OFF.
Press the recirculation control switch and the rear window defogger switch.
While holding the both switches down, turn the ignition switch ON (II), then release the both switches. The recirculation indicator light and the rear window defogger indicator light come on. The recirculation indicator light goes off 2 seconds later and the A/C indicator light comes on (if so equipped), then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator light goes off. The recirculation indicator light will blink the Diagnostic Trouble Code (DTC) to indicate a faulty component. If no DTC's are found, the indicator light will not blink.
NOTE: LHD type is shown, RHD type is symmetrical.

Example of DTC indication Pattern (DTC 3)



Resetting the Self-diagnosis Function

Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sure that there are no other malfunctions.


My tech manual has pictures that I can see, but I can't get them into the post quickly.... Follow that for the self diagnostics, put your code in this thread if you have one. I'll look it up.

Here's the codes for a 2001 EX sedan. Yours may or may not be the same, depends on US of Japan build I would think..

Rahway09

so i did the test and the recirculation button blinked 12 times.

ezone

Code 12 is defined as "A problem in the blower motor circuit".
It can't tell you WHY it doesn't work, only that it knows the problem is in that area.

As I said before, the blower fan must be fixed first.

Mine blinked 9 times. What would that be? Thanks

Thanks ezone!

landt222

Also, for code 9, are these items all accessible behind the glove compartment? Thanks

landt222

And from this parts diagram, which part would it be? 13 or 14?

Thanks for the help.

ezone

#13 says " MOTOR ASSY., MODE" This one changes modes from dash vents to floor, to defrost.
#14 says "MOTOR ASSY., TEMPERATURE". This is the air mix motor.
You would see this one from the drivers floorboards while laying on your back, looking up.
