Air con blowing warm air

[Pauluco]

Hello , I have a 2015 berlingo 1.6 HDI , I’ve recently had the air conditioning tested for leaks and regassed , fitted a new air conditioning pressure sensor , a new radiator fan relay , the air con clicks  on when pressed on and everything starts to work seems to run normal , it just doesn’t blow cold air , the radiator fan only kicks in when the engine reaches 90 degrees , I’ve had a few hours searching online and found that the radiator fan is supposed to start on low speed when the air conditioning is activated, mine doesn’t , I’ve also found that there is 2 resistors one for high speed and one for low speed , but I can’t find where they are located, any help would be much appreciated, thanks

Thanks for that , I’ve already changed the radiator relay , and the fan works as it should when the engine gets up to temp it kicks in , it’s just not working on low speed when I press the air con switch on , I’ve found a part number for this (6547TX) but I can’t find where they are located on my van

Have you got the auto air-con with the controls like in this image?

No it’s just a single on off button with a green LED light when it’s turned on

Okay, are you saying that when you switch on the air con, nothing happens or are you saying when you switch on the air con and put the blower into say speed 1, 2, 3 or 4 nothing happens? 

On my Berlingo Multispace you had to switch on the aircon and select one of the blower speeds to get an output, it never switched on the blower for the air-con by just putting the air-con [green LED light switch on]

If you are saying it doesn't work on a certain speed, say speed 1, then it will be the blower resistor, located in a duct on the driver's side foot well [on a Right hand drive car] and quite awkward to get at [but is relatively easy to replace once you locate it, only held in by one screw which from memory was a small size torx head]   

If it doesn't work on any selected speeds it will be the blower relay which is located on the passenger side [on a Right had drive car] up in the lining behind the glove box, which requires you to take out some of the lining. Again relatively easy to replace once you find it, it is just a plug in type relay.

The air con is working as it should on all 4 speeds and when turned on the switch I here the air con clutch kick into action , but the radiator fan is not turning on low speed as it should when the air conditioning is activated , but the air con is not blowing cold cool air , I can’t  find where the resistors are located on the van , it’s supposed to have 2 resistors for the radiator fan one for high speed and one for low speed any ideas , thanks

The in cab blower 1-4 is working and blowing air , the air conditioning is working and clutch spinning , it’s just not providing cool/cold air , from searching online all I can find what the problem will be is the low speed radiator fan resistor for the engine cooling fan , it says on my searches that it’s supposed to start on low speed as soon as the air conditioning is activated

Does anyone know where the 2 radiator cooling fan resistors are , Ive followed the cable from the radiator back to the fuse box and can’t find any resistors , I’ve even checked the Maxi fuses under the fuse box all in good working order , it’s just the low speed fan what is not turning , when the van is up to temp the radiator fan turns on full flow
