Radiator Cooling Fan Won't Turn Off (2010 Volvo XC60 T6)

Post by ClarkKent » Sun Sep 02, 2018 8:47 pm

HELP - I've seen a few similar posts and don't know if this is the same problem or something else? I detailed my situation down below. I'd prefer to NOT replace the whole unit if I can go in a different direction.

2010 Volvo XC60 T6 (59K miles) - Engine cooling fan won't shut off. The LOWER RIGHT fan is the one that won't stop while the UPPER LEFT one has stopped. To completely shut off the fan, I disconnected the battery (+). I reconnect the battery, and the fan still runs without turning the car on. Previous posts say you need to replace the whole fan unit or shroud. My initial over the phone estimates FROM NON-DEALER Volvo specialists were about $1000. PLEASE HELP - any and all feedback is greatly appreciated.

- Could this just be a fuse? (I doubt I could be that lucky).
- Good PRICE ESTIMATE for parts and labor?
- How many ESTIMATED LABOR HOURS? One specialist recommended 3 to 4 hours while on other sites it seemed fairly doable from a knowledgeable tech, it just took extra care moving the cables and getting it in properly behind the radiator.
- One place said he could check the valve/sensor and that would be around $450 but, almost always just replace entire fan unit for the $1000
- Any feedback regarding www.yourmechanic.com to do something like this?
- ANY OTHER VIABLE SUGGESTIONS (lose cable, worn out clip, etc.) TO LOOK AT IT??????

I'm no mechanic but, good at working through things. IS THIS DOABLE FOR A DIY PERSON as I really can't spend the $1000 at the moment. OR, WOULD YOU RECOMMEND AVOIDING THE HASSLE and PAYING THE SPECIALIST????

THANK YOU SO MUCH IN ADVANCE!

That it is on immediately when battery is connected again pretty much rules out the ECM commanding it on in error. The symptoms of bad engine coolant temp sensor is the fan running once you switch on ignition and then running after ignition is turned off for 3-6 minutes. But that would be both fans running. Your listed symptoms pretty much point at the transistor controller circuit having a meltdown.

Cooling Fan Control Module. You can get aftermarket replacements on eBay for $22.00. Or you can do it the Volvo way, buy the entire fan assembly for ~$200.00.

Thank you so much for the initial feedback. Please forgive me as I don't fully understand some of the terms used. Initial quotes are everyone saying you need to replace the entire fan unit/shroud - that's $500 for parts and 3 to 4 hours labor for another $500. Seems WAY OUT OF LINE and willing to try alternative approaches.

Here is the full breakdown.....

- Connect battery...RIGHT side fan turns ON and LEFT side fan stays OFF
- Turn ignition on....RIGHT side continues to TURN, LEFT sides does turn on & once car is warmed up the LEFT side stops (THIS IS NORMAL)
- Turn ignition off....car power shuts down as normal, and RIGHT side continues to TURN. The ONLY way to shut the RIGHT side down is to disconnect the battery.

The cooling fan control module seems like a viable option, and I DON'T want to replace the whole fan at $1000 if I don't have too. Ironically, it doesn't seem that complicated and these estimates seem inflated. YOUR INPUT IS GREATLY APPRECIATED!!!!

The transistor circuit in the fan control module that is mounted to the fan shroud/fan assembly can and do fail in a way where the transistor circuit powers fan all the time. On that car there are two fans so there are two circuits in the fan module. The left (larger) fan is working as it should but the small fan's transistor circuit is shorted and is not turning off the power. You can find some sources of the module only and with 59K miles that might be a good option. Way cheaper too. I have seen XC60 and XC70 fans fail at over 100K fail like yours (stay on) and the fan motor was dragging and noisy and that result in higher current flow that fries the module.

Thank you and I apologize for the additional questions. Please see the additional pictures - IS THAT THE CONTROL MODULE YOU ARE TALKING ABOUT (in the circle)?

If so, I've seen them posted in the $25-35 range which is terrific https://www.ebay.com/itm/New-Cooling-Fa ... 2273328715. Can this replacement be handled by a novice or do you recommend taking to a skilled technician? If need professional, how many HOURS labor? Two I talked to were adamant over the phone about replacing the entire fan shroud.

That is the module. The connectors each has a latch you depress before sliding them off. The to lower ones have the latch facing back of car between where the two wires are loacted in connector. The top one has the latch facing the front of the car in similar place. Torx 25 screw hold it to shroud. I have a $20 Kobalt multi bit ratcheting wrench low profile kit. It has a set of screwdriver and torx bits and uses a ratcheting boxed end wrench where the bits fit. The clearance bwtween rad hose and the module is a little close. I can get my hand in there but it is not enough for a torx bit of normal height and a 1/4 inch regular ratchet to fit.
Look at Item # 239459 on lowe's website. That is not what I have but it will work if the torx bit size is right. They sell individual torx bits there.
No programming or anything to do. No real exposure to bare wires so just have ignition off when you change it.

Yes that is the control module.

Can this replacement be handled by a novice or do you recommend taking to a skilled technician?

If the novice has any mechanical aptitude the novice can do it. It pretty simple, if one cannot figure it out, auto repair is not one's thing.

how many HOURS labor?

I would take me less then a hour.

Two I talked to were adamant over the phone about replacing the entire fan shroud.

That is the Volvo way. You cannot buy just the control module from Volvo. That is why I said Aftermarket. If you want to replace just the control module, you will need to get the part yourself and change it yourself or have a independent shop change it for you.

Hey guys,
I have a similar issue but my problem is the bigger fan doesn't work. I already bought a new relay and installed and tried it but no luck. The bigger fan is shorting out I guess because I saw some small sparks. The smaller condenser fan works fine.
I am going to have to remove the whole assembly. What I am looking for is some guidance about removal process because I see some AC lines on the ways. Will this fan assembly come out from the bottom or have to deal with compressor to make some room and pull it up? Thanks in advance.
