The air does not come cold, the light glows on the button but the air is at external temperature.
Already checked all fuses but I can't find in the manual wich fues or other connection I should check, what else?
When you press the air button does the compressor actually cycle on? If not may be low on R-134 or some other issue.

I have to check, but I am new to this car, got it in december and stayed at repairing in the last month, so I am not sue of which is the compressor and where to find it, it is not marked in the manual.
I generally encourage the do-it-yourself option when possible, but if you honestly are not sure of what an AC Compressor even looks like you may want to stop where you are or get a friend that is knowledgeable. AC can be dangerous if you are not sure what you are doing.
AC compressor is front top. You should be able to watch it with AC off and see the drive pulley turning, while the outer part, the clutch is not turning. Have someone turn on the AC. The clutch should emit a loud clack, the engine will drag slightly (can usually be heard even from inside the van) and the clutch portion should lock in and turn with the drive section.
A quick test to confirm if it is low pressure in the system is to remove the connector from the low pressure cut-off switch and put a jumper on it. Have someone turn on the AC while watching the clutch again. If it starts now you are low on pressure. Don't let it run more than just a few seconds with no pressure in it.
You need to go to a repair shop. They will most likely tell you you need an evaporator. It is an expensive repair, so get ready.

This is what I needed to know thank you, I will have a look asap.
Just curious why you feel they will "most likely tell you need an evaporator"? I am currently on my 4th Caravan since 86, all have been well over 150k miles on them and none ever needed an evaporator replaced.

maybe that they just want our money? :)
Starting in 1994 with R134a freon, Chrysler evaporators started failing left and right. I noticed the biggest problem with the LH body, but it seemed no model was immune from it. And yes, specifically I have fixed a number of 94-95 Chrysler minivans with failed evaps. I don't know about after the body change in 1996.

If this is my problem, what do you suggest to be sure it is fixed in a way that doesn't brake again for the same reason?
When I was replaceing them years ago, I tried the aftermarket and they only had reboxed OEM cores at the time. I don'r know if you could get an updated part now. Even a poor quality evap core that holds pressure out of the box will probably get you to the point where you will sell or junk the van, so I wouldn't worry about it.
