well the other day i was getting breakfast and in the drive thru my temp guage went above the fan cut in and the fan didnt turn on...only thing is i didnt get a warning it failed...no whining...no constant running after it turns off....no weird noises....just stopped working...once i get going again the temp drops back to normal but no fan!

\any ideas?i think it might be a relay

 

Well, start off easy and see if you can still turn the fan by hand. Then, check the fuses. The relay should be pretty easy to check as well, although you might have to temporarily scavenge one of your other relays to test with.

Does the fan still come on when you turn on the air conditioning? If it does, your problem might be with the coolant temperature sensor rather than the fan itself.

 

thanks for the tip ill give it a shot

 

i dont think its the coolant temp sensor cuz i have a scan guage and it reads the coolant temp just fine...the fan just isnt kickin on when it should

 

Give the air conditioner test a shot anyway. There are often multiple coolant temperature sensors in the car - the fan circuit might have its own. I know that the coolant temp sensor that drives the temperature gauge in my car's Chrono Pack is different from the one that the Scangauge reads.

 

Scott is right, there is usually a coolant temp switch and a coolant temp sensor. The switch controls the fan and the sensor gives the computer a gauge reading.

 

well i went out last night and cranked the engine over and turned on the aircon and the fan was running....so i know the fan ckt is working like it should...where is the coolant temp switch or sensor i was looking on realoem and couldnt find it....any ideas?

 

well i took it to miniwerks here in clearwater and after some electrical tests the fan is starting to die...u can hear it like it wants to click over at the stage 1 threshold but wont...but it will come on at the stage 2 threshold(233)...besides the dealership any good place to get a replacement fan assembly?

 

I also need a new fan assembly, where would the best place be to get an OEM one?

 

Ouch, the OEM unit is $278 @ ECSTuning. It looks like it might only come paired with the housing. It's a little more at PelicanParts.

 

the thing is if the original manufactor can be found i bet the non MINI branded one will be cheaper

 

You can find the fan unit at www.rockauto.com for $110. I'm not sure of the quality though but the OEM quality level isn't all that great anyway. Not only that, I don't think the geniuses at MINI/BMW designed a check loop to warn the operator that the fan is faulty... same with the P/S pump fan.

 

Actually the ECU is the only thing that controls the fan; it does so with a input from the ECT sensor or input from the freon pressure sensor. Data from the ECT sensor is used for the gauge as well.

 

my fan is about done...its alittle too loud compared to what it used to be plus it has lost its stage one turnover...only comes on in stage 2

 

Does anybody know of someone who has successfully installed the RockAuto fan on a 2005 or later MCS?

I saw a thread yesterday where a 2003 owner said it wasn't a direct install because it was missing something but someone mentioned those parts weren't needed in 2004+ cars so it "should" be a direct fit...

 

I've read that the Low speed is activated by a relay in the fuse box inside the engine bay. Have you checked that yet?

 

all the relays check out...in fact there are 2 relays that control stage 1 and 2...the relays were swapped around and the same effect happened so i know its the fan...plus the sound its making isnt good either

 

I cannot believe the short life span of some components on the Mini. The fan motors on my 1987 Porsche 944S (126k) and 2001 VW New Beetle (154k) run smooth.

 

actually my fan on the mini lasted 103k miles so i got plenty of life out of her

 

in fact...knock on wood...my clutch and flywheel has lasted 104k and still goin

 

well i went ahead and ordered the Rock auto fan...i talked to the sales lady to figure out the difference between the two versions(standard and econ)...the standard is built to OEM specs while the econ is the cheaper version...the reason for the price diff is because of the various companies and warehouses they deal with...one price could be lower but if they run out and go to the next company it could be higher

 

Well i just got off the phone with Classic MINI Auto Campus which is a NAM Vendor. They sell the MINI fan for $291 - 20% NAM member discount which comes out to $232 which is a hell if a discount.

Even with the discount though i think im also going to try the RockAuto part and hope its a direct fit. At worse i hope they are good at taking returns. Right now the $100 savings is pretty decent.

 

Well i guess maybe not, looks like yellowrocket may have gotten the last one as RockAuto isnt showing the part number being in stock anymore.... :(

 

sowwy...if u give them a call they said they have multiple vendors...they say its built to OEM spec so we shall see

 

well the fan from rock auto came in today...and was suprised...i know some people were worried about the quality...

the fan isnt made by rock auto...its made by TYC! for those who dont know the name TYC is a big company in the import world...so the quality is very nice...it feels very sturdy and not flimsy at all
