Hi all I need help with cooling fan problem.
Only works on high speed
Anyone know relay location and any tips or advice
Two litre hdi Berlingo multi space with aircon and single fan
It don't run with aircon turned on either
Thanks in advance

Re: Berlinger 2.0 hdi cooling fan
Ok, so you have Peugeot Partner (same as a Berlingo). This model has a twin speed 140W Fan. It has 2 relays, one for slow and one for the fast speed:
Click Image to Zoom On the diagram above:
1509 is the fast speed relay
1508 is the slow speed relay
1506 is the Fan 2-speed resistance
So looking at the diagram below, you can see which relay is the slow speed one. So 1508 is the one and it is nearest to the actual fan itself (bear in mind the diagram is looking at the fan assembly from behind).
The relay is a 35 Amp unit and identical to the fast speed one.
It is part number 6547TX and is £8.99 for a genuine one available from any Peugeot or Citroen Dealer inc. VAT

Re: Berlinger 2.0 hdi cooling fan
No worries - it should be easily enough to replace, but the wiring can suffer on these given their location to the elements - so check those out to.

Re: Berlinger 2.0 hdi cooling fan
Check out also the slow-speed dropper resistance (#1506). These can burn out or go open circuit, and their connectors deteriorate with heat.
The relays are cheap enough from Peu/Cit, but are also standard 5-pin 12v 30/40A automotive type, so any motor factor (or electronics dealer) should stock them.
All the blade contacts on these "front end" items can suffer from heat, wet and weathering, so best to clean up any involved.

Re: Berlinger 2.0 hdi cooling fan
Would it be the resistance though if the high speed is working Chris? I think these earlier Berlingos had a simpler unit over the variable ones in later cars with climate and the like.

Re: Berlinger 2.0 hdi cooling fan
From the diag above, the +12 supply is routed to the fan (from the low speed relay) via the dropper resistor.GiveMeABreak wrote: ↑03 Oct 2019, 17:40 Would it be the resistance though if the high speed is working Chris?
For fast speed, the fast speed relay routes +12 directly to the fan, by-passing the resistance.
So, if the resistance fails (open circuit, or poor contact), low speed operation will go missing, and the fan will not operate until high speed is triggered.

[[/img]Hi
Update Removal and inspection of all 3 items
Relays removed and given a supply and they both move and make contact using a multimeter.
Large resistor removed and tests out at 5 ohms.
Its quite mucky though with green corrosion near the large resistor tails.
I am unable to see if it has any effect as the engine is out for other repairs. All your information has been valuable, especially the component locations.
I will be able to power it up when the engine is fixed and replaced

Re: Berlinger 2.0 hdi cooling fan
Great, do let us know, I’ve never seen one of those older resistors up close, so will be interesting to see if that’s your issue.
