Help! High speed fan won’t cut off; battery dead now!
Turned engine off and noticed HS fan was still running. Had to leave car for 40 mins, returned to find fan still running but not enough juice left in battery to start her. Waiting for breakdown now. Sigh....

Use a torx screwdriver to unscrew the 80A fuse (FL4) in the engine fusebox.
That should stop the engine fan. Last edited by MarkS; 18th December 2019 at 12:20.. Reason: FL4 |

Quick look at my fuse box suggests fuse 4 feeds the fan but also the auto box, so we'll forget that one. Any chance you can remove peel back the wheel arch liner and reach / separate the two large fan connectors just to get the fan to stop? (or even access them from below through the triangular finisher). I know it's not a good idea to run without a fan, depends how far you are from home.

I'd suggest you check/test/swap the relays in the control box (front bumper off, etc.)
There are lots of threads on the issue, so worth a keyword search. TC |

Actually, the autobox (and everything else it seems) runs fine without that fuse so I've put it aside and turned on the real-time temp sensing to continually monitor the coolant temp. I'll just kill the engine if I get stuck in traffic. It's not the time of year for getting things like this fixed relatively quickly unfortunately!

I'll have a trawl thanks.It must be something about the sh1t on the roads that gets to our cars at this time year. First it was an ABS fault that turned out to be a rear wheel plate problem, then the reversing sensor started to play up and now this fan business!

That 2-speed unit should be plug'n'play to your system, however the silver resistor will fail pretty quickly and will have to be replaced. When that happens, the slow speed won't run and you're back to square one. You ought to get the uprated resistor before you fit the new fan. Check through eBay again for the gold type or check out the forum traders, electronics outlets (eg Farnell). TC |
