citroen xsara mk2 - problem with the installation of air conditioning

Post by kuba2704 »

Hello, I am just installing the automatic air conditioning in xsara and unfortunately I have a problem, according to my diagram, you need to connect the plus to pins 2 and 4 to the blower controller. but from what I was able to establish pin 2 you need to connect to ground. one more pin comes out of the fan (a thin black wire connected to the mass of the fan, the fan is obviously grounded) And now I have a question where to connect this cable, unfortunately I did not find an answer to my question in any diagram,
I would like a quick answer as I am not able to make an air conditioning package.

Sorry for my english, i live in poland

Hi kuba and welcome to the forum
Could you post the diagrams so we can see what you are working from.

Your English is fine :)

You need to log in to see the diagram?
Are you fitting AC to a car that never had it or are you changing regular AC to the automatic AC?

Sorry for the bad link to the schematic, it should be fine now. This is how I put air conditioning into a car that never had it.

the fan is marked with the number 8045

Have you fitted the A/C ECU & harness?

Sometimes when you buy a new motor it comes with an extra link wire, ive never come across a car it fits on.
It looks like pins 1 & 3 go directly to the A/C ECU and pins 2 & 4 are a live feed which on the Xsara should only be when the engine is running.
I’ve never understood why car manufacturers make cars that allow you to operate the heater blowers & heated rear screen without the engine running, seems to be a PSA thing to work with engine running only.
