Keep popping fuse (climate control) when stopping?
« on: 06 January 2009, 12:48:29 »

The climate control has always been fine, then one day flicked off as we were driving, pressed the buttons and it came back on, did this for a few hours then died. Changed the fuse ( no.14 30amp ) for a 25amp as it was all I had, went to the south of france just fine, worked for a good few months.

Went to start the car and no panel display for climate ( everything else ok ) and no control of vents air temp etc. Changed the fuse and it popped straight away, changed it again and it was fine, drove back from dorset no problems.

Get to fulham stop at traffic lights and it goes off, press buttons nothing, when moving it came back on, stopped, went off etc, til it wouldn't come on.

Change fuse and started it cold this morning, popped, let the car warm up, changed it and it was fine, til I stopped again, went off.

Got to work and it works when moving if I switch it back on, but as soon as I stop it goes blank and will eventually pop the fuse.

Any ideas ? I thought about just sticking in a breaker fuse ( trying to find one at the moment, any ideas ? ) rather than just replacing the fuses.

Also this all seams to happen when it is very cold outside ?

Sounds like it is activating a circuit with a fault under some conditions only. Trying to think what it could be...

One possibility.. do you have the auxiliary coolant pump on the driver's side inner wing (just under the expansion tank)?

Just wondering if it activates this when idle to supplement coolant flow in cold conditions. If the motor has died it could be drawing excessive current.

Might be worth unplugging the pump and seeing if that stops the fuse popping.

I assume the heater blower works fine and isn't making any nasty noises? Not even sure it's on the same fuse, thinking about it. :-/
