MINI Cooper Electrical & Lighting Glitches



  • plsmrvllplsmrvll Posts: 3
    I have a 2009 Cooper S. Has anyone else experienced an electrical 'clicking' sound, like a relay turning on/off, from the passenger side compartment? Had it in for service and they didn't find it. It's intermittent, and it clicks several times when it happens. Hard to pinpoint it, but I'm thinking it has to do with the fan/AC.

    Thanks in advance,

    Can't help you there, Pat. :confuse: You said it's intermittent--does it ever occur when you turn on the heat (assuming you aren't in a tropical climate just now)? I'm trying to remember if my '06 S ever did that, and can't come up w/anything. As usual, you can NEVER duplicate what's happening when you've got a tech there ready to help.

    I'm sure some of the more experienced folks in the community can help. Are you registered on NAM? There's a multitude of information there. I hope the clicking gets taken care of, cuz I'm sure it's annoying you to no end--it would 4 me! :shades:

    Hi, both electric fans are not working. My mechanic has done all the basic stuff; straight wired them (they work) checked relays etc. There is a low pressure switch
    on the AC that should send a signal for the fans to come on: also the radiator cooling fan is not working. Any help would be appreciated.
  • I have a different problem and I am at a loss to figure it out or know where to start.

    I have a whirring noise when my 2004 MCS (r53) is off. It simply started without any notice at all. All the car was fine, parked it, whent into the office for a few minutes and back to the car and the battery was almost dead. The whirring whining noise was there. car barely had enough juice and eventually couldn't. Got it jumped and it runs perfectly. drove it home and I let it idle for an hour. turned it off, waited 10 or so and it happened again. this time, when i tried to start it the headlights flashed, next time the driver window went down 1/2" at a time in the same beat as the starter, next time the wipers went in time to the starter.

    jumped it again and it ran fine. Looked at the battery and the indicator was black (I know they arent all that reliable). put a volt meter on it and 5.5 volts. Ah dead battery. Jumped it and headed to the autoparts store. took the battery out and had them test it... it was GOOD.

    The sound sounds like a relay or switch not turning off when the car turns off. I live in a small town, only mini, maybe 1 of 2, hard to find a foreign car mechanic. Couple of questions:

    anyone recognize this issue?
    Will a real electrical diag be the right direction to go?
    Will Pulling codes help?
    Any ideas? I fixed a pass window issue by finding a blog that said, bang with your fist just above the speaker on the pass door - it worked :)

    I have reset the ECU, I noticed there are some diags under some of the options.

    Help! I love my Mini and hate my work truck which i am now driving! THANKS IN ADVANCE!!!

    Could that be your radiator cooling fan operating? If so, and you own a 2004, I would check for low coolant level, caused by a small thermostat housing leak.

    If the engine is too hot when you shut it off, that cooling fan can run for 10 minutes easily and it draws a lot from the battery.

    If your battery is the original one, then it's toast anyway---too old.

    The car in question has 140xxx miles on it and has been having issues with the lights turning off when in use at night, the power windows won't go down anymore and the battery has a drain. If anyone has had similar problems and found an answer please let me know thanks!
  • I have a similar issue with my 04 Cooper S after having it jumped. The battery seems fine but windows won't roll down at all. I called a trusted Mini mechanic and he said to try disconnecting the negative battery cable for 2 minutes and it should reset the windows. I haven't tried it yet but will let you know.

    Maybe this is common knowledge, but new to me. Cooper 2003. Light control wand suddenly messed up. Right turn click seemed to work, but Left turn click brought up brights. Bright click brought up hazard lights. One parking light came on after car had been parked for an hour. Strange stuff. Disconnected positive battery lead so battery would NOT drain overnight. Re-attached in morning and all was well. Apparently, it re-booted.

    Probably not a good idea to disconnect the battery since that would erase whatever trouble codes might be stored (if any), which can give you some idea of what might be going on here.

    In any event, let sleeping dogs lie as they say. I also have a 2003 Cooper S and electrical glitches just come and go all the time in my car. I have no idea if this is due to bad grounding, a short in a wiring harness, or just the fault of the blind men who built this car in the first place.

  • I have a problem with all the lights on my 2009 Clubman. They are always all on if the car is on. When I unlock the doors or open the barn doors, the headlights, tail lights, brake lights, dome light, side running lights.... all come on. I cannot find a way to turn any of them off. It doesn't matter if the headlight switch is set to on, off or automatic, they still stay on while the car is on. After I shut the car off, they all stay on for a short time (10 or 20 seconds maybe). Because all the bulbs are lit all the time, applying the brakes or switching the directional lever doesn't change the lights, although the little arrow on the dash does flash as if the directionals are working. Any Ideas? The car sat unused for a week before this problem arose, and the last thing I did with it was to jump-start another car.

    You're going to need a full wiring diagram for this problem. You will (or someone will) have to figure out how the signal to the interior lights and dome lights (normal operation) is being hijacked to the other lights.

    You might be able to find the wiring diagram HERE, or your mechanic can call it up from his database. Ifhe is flummoxed, then you will have to go to an electronics specialist.

    You may find one in your area from THIS LIST. These people are the best in the business.
