Radiator fan control / AC not working
Hello all
i have a 2011 XF Supercharged. The AC hasn’t been working well at idle or low speed. If moving at about 45 or more it works fine. Took it in and had it checked, was told coolant was fine, compressor working properly but fan is not working correctly. Any time AC is on the fan should spin, correct? It does not. As engine warms fan engages but seems to be on low.
I changed the fan but the new fan does exactly the same thing.
So now, what tells the fan when to engage and what speed to run?
is there a fan control relay or something?
any direction would be appreciated!

Pressure switch
I had the same issues. That it was the fan, then thought control unit, but it was just the pressure switch on the back of the compressor. Much cheaper fix. There was a tab for it.

Try pressure switch first.
New 2013 XF V8 5.0 Supercharged owner here. Purchased this vehicle on 05 July 19. I have yet to receive it from the dealer due to the same issue with the air conditioning which I witnessed on the initial test drive. At first they said it was the expansion valve under the dash so they pulled it (expensive) and replaced the valve. It still did not get cold while sitting at a light or idling. They then replace the fan and had the same results, no change. The next time I visited the Jaguar dealer the technician was putting the air compressor back in. He then told me that the pressure switch on the air compressor was faulty and replaced it. Bingo! It now works as it should.
I have had lots of waiting (patience) while this ordeal has gone on. Ordering and waiting on parts etc. When it left the Jaguar dealer it went to the high end collision center to have some minor scratches taken out of the rear corner panels. I found out today that it is complete but not yet ready to pick up. Turns out that the right rear wheel has had a repair (weld) done to it and after they put the new tires on it it began to slowly leak air. Much to my surprise they have now ordered a replacement rear wheel which should be delivered early next week. I was shocked when I learned that one 20" rear Draco wheel is $1,000.00.
I cannot tell you how excited I am to finally receive this beautiful vehicle. Having only driven it one time, the day I bought it, I have been a daily reader of this forum and have learned much. I imagine that I will have questions once I do finally receive my purchase. Thanks for sharing all you owners do here. First time Jaguar owner and Thank God the dealer is paying for all of this work to be done. There is no way on earth they have made any money on this. Lost money for sure. They will get an excellent review from me.
I don't mind waiting, it is going to be worth it.

Good luck.

The mechanic also thought that his air conditioning charging unit was not putting enough Freon in the system when he initially started to diagnose the problem (this was before the new fan and compressor pressure switch but after the expansion valve replacement). He figured that someone must hav walked by and bumped his charging station causing it to give bad readings on the recharge. This was not the case though. Within the next week the fan was replaced but still no different. The following week the pressure switch. If I was doing this myself you can bet I would replace the Pressure switch first. Just as VPinGA states "Much cheaper fix".
