I had no lights on my clima control.(no climatronic)

Could be internal or just a bad connection at the plug.

masculino el clima nadie dice la clima

U HAVE A CLIMATRONIC OR A MANUAL ONE?CLIMATRONIC IS WITH THE TWO SCREENS!!IF U HAVE THE CLIMATRONIC THERE IS A SERVOMOTOR THAT CONTROLS THE HOT AND COLD !!! IF POSSIBLE SEND PHOTOS

Does the moisture smell link coolant?
Use a white napkin and wipe the inner windshield,
Compare the color to your coolant tank.
This will verify is this a heater core problem

===========
Next item that can trap water is the A/C drainage problem.

You will need gloves for this.
Most A/C drain is ion the bottom of the center console.
The bottom of the tray is a A/C drain tube and pan.
Check for drain blockage. (DIRTY JOB!)

I hate to state the obvious, but it sounds like it was not reconnected. There are 3 possibilities, no power, no ground, or bad fuse.

Hi,

you carnt replace them they are part of the control head

i had exactly the same problem and i solve it 3 days ago. the buttons were not responding. what you need to do is to open the front panel (not so easy job. take out the radio first and then the aircon/clima board. you will need extra care not to lose the small parts) and you will see under the buttons some metal contacts paired with some plastic joints that are not any more in the correct position: your buttons are not returning in the upper position.
The small metal parts under the buttons should push back the plastic joints but yours are not doing the job anymore.
Make sure that all the sides of the small metal "v" shape springs are under the plastic joints. Put everything back and should work.
Before mounting everything back you can test the PCB by connecting the contacts manually. You should see the status of the leds lights changing. If the PCB is working then you will be 100% sure that the reason are the buttons.

I need also help to find the A/C electrical scheme for an bmw 1996 E39 auto climatronic. Thanks.

it should be number 42
