The heating in my Mini One has stopped working. I have done some investigation with my partner and so far, this is what we've found and I'm hoping someone might be able to help. A few of the things we've tried so far have come from posts we've read on this forum but still no permenant fix.
1. The car reaches temperature as normal, the needle sits in the middle of the temp gauge and doesn't take any longer then normal, approx 5mins from cold.
2. The car has the manual 3 dial heating controls. When driving, my partner was testing the heat control, and at some points, very briefly, hot air did come out, but after 10 seconds or so, it would go to luke warm. We put the heating dial back to cold, then few seconds later, back to hot. again, hot air for about 10seconds then back to luke warm. On a 3rd attempt, no hot air, just luke warm air.
3. A/C is OK, not as cold as it could be, but you can definitely feels its colder then normal cold air when heating dial is in the blue.
4. We've checked under the bonnet, checked the fuses and relays, reseated the relevant ones, no difference.
5. The only thing we've noticed that could be an issue is the coolant level, it's over an 1" above the max line and it's the same whether the engine is hot or cold. My partner located the bleed screw (if thats the correct name) on a pipe exiting the radiator. On first undoing this, there was quite a bit of air until fluid starting coming out. This didn't appear to make much difference to the heating so we tried bleeding the system again with the engine running. more air came out at first, then fluid. We tried the heating and it still does the hot for a few seconds then back to luke warm. Is there any ideal way to drain coolant? short of running the engine and letting it run out of the bleed pipe?
6. Occasionally after even a short journey, when I turn the engine off, the fan kicks in for about half a minute. This doesn't happen all the time and has only starting happening for just over a month now.
The whole heating issue has started since returning from a 3 week holiday, so the car was sat idle for 3 weeks, not sure if this would point to a cause?
If anyone has anything else we can try it would be appreciated. just spent £200 on a new exhaust so if i can avoid another trip to the garage then great.
Thanks in advance
