This friend sounds really knowledgable, could he join the forum for a hearty welcome
I drive a Seat Alhambra 1.9Tdi which has 115bhp and an automatic gearbox.

I am happy to help you with all your questions. I am not a qualified mechanic but seem to be better at fixing my car than even the most experienced garages.

I have lots of friends here and very much enjoy talking with you all.

Always remember, a motor car is a serious tool and should be treated with respect. Put your safety first, always.

Hi Joker. I am really starting to desperate. I looked in a program called autodata, in haynes manual, and on every corner on the net and I found nothing. I look for a box of relays somewhere but unfortunatly nobody can help me about that. I was aware of the box at the drivers knees but those are just fuses. I will keep looking for. Thanks anyway. by the way, number 30 in my car (from germany) is for the music console.

There are relays down by drivers knee,they are located above the fuses and I suspect this is where you will find air con one.

If you can find a copy of TIS (I have one, but can't get it to load at the minute) there are wiring diagrams on there. Haynes isn't much help, it just lists a few fuses and such.

Might help to know what your trying to fix - its obviously an aircon problem of some sort, but if you can give some symptoms it may help to point you in the right direction.

Ohh thanks I was getting crazy. I asume this pictures are from a car with steering wheel on the right hand. It is weird for me but at the end It is the same the other way arroung. I guess tomorrow I will get throught every step shown in the pictures and explanations to discover the relay in cuestion. the thing is that my aircon is not working at all. A friend checked. He then told me to ch the compresor and was okeck the relay. He put some gas in the circuit since It was almost empty due to a leak I asume. For the moment we are focusing in electrical components to discard some issues. Sorry about my English. I will let you know how the things go aroung. thanks. oscar

So the air con was low pressure and you had it gassed up,has the gas stayed in can you confirm if it is still pressurised?
Have you run diagnostics to see if any faults?

Could be pressure sensor fault as this will stop system working,take out offside wheel arch liner and check for power in and out of pressure switc. If I remember correctly it is a combined high and low pressure switch so a healthy system should have 12v out to energise the relay. If switch is not working you can change without degassing.

Is it climate control or manual air con? If climate does panel flash when first turning car on?

hello johnnyroper.
we had it gassed up but did not checked if stayed presurised yet. i will run diagnostics this week.
thats a good idea to check presure switch. It is climate. when turn on no panel flash. thanks.

No panel flash suggests there are no faults logged, have you tried checking for power directly at compressor? If 12v there system is good and compressor is not functioning. If no feed then start working backwards

hello Johnnyroper,
I managet to get to the relays (I check those numbered 100 and they were ok)
A friend helped me to check that the compresor clutch engaged as normal.
for the moment I am watching lots of videos in youtube to understand the whole system, therefore I came up with some new ideas...I recomend this guy from the states:
https://www.youtube.com/watch?v=SftAZG4h-eA&list=PLaRuYYPxjXI2U7uMGm7YOqEn5CIJEY-RP&index=10
I try to absorv as much informations as I can.
when I got the car I was cheated just for trusting the seller (particular) without checking almost anything. the thing is that thanks to that and the great support from this forum and people like you I have learn a lot. hopefully I will get involved the more and more into mechanics because It is fun to overcome this challenges. thanks. oscar

hi Johnnyroper.
sorry about confusing you. Actualy a friend was checking clutch engaging as he energisized compresor'conector from batery and as a resoult he was able to heard some clicking so the coil should be ok. On the other hand, I realiced today that with the motor in idle position and the A/C system on at maximum the pulley wasn't egaging the clutch at all. I atempted to dismantle the presure sensor and what I found was a coupling next it (high presure line conexion I guess) rather greasy. that must be a leak. I dismantle the presure sensor but I don't know how to check it in case it doesn't need replacement. thanks again. oscar

So putting feed direct has proved the clutch but you still don’t know if system is still pressurised or if there is 12v getting to compressor.

hi Jonnyroper,
I decided to restart again by checking all the things from the begining.
 I was checking a picture (fuse box) from this thread (Ford Galaxy - Gaining Access to Central Junction Box Fuses & Relays (Mk2)) and I noticed some discrepancies.
I checked every fuse with the multimeter and all of them were right.
I downloaded a chart from this forum related to fuses numerations and found out that #16, BLUE, 15 AMP was missing. Maybe I should have started from this point.
On the other hand, I ordered a kit from amazon. A set of manifold gauges and a leak detection. I already have a vacuum pump so I will run every step myself to make sure everything is done properly.
I atache a photo of my car's fuse box in case anybody notice something wrong.
thanks again and sorry for being so erratic in dealing with this issue.
