And... is the climate control unit programmed? Had the battery out for a few days while I worked on a few things in the trunk and I have nice cool air through the vents but hot air through the floor vent.
Thanks
Nothing on an E39 528 of that age normally gets effected by a complete power down apart from the radio station memory.
The fan should run all the time the AC is selected and if the rad switch calls for it too. You need to check the relay block is getting a signal when the AC is switched on. But I think both this and the signal from the rad switch come via the main engine ECU.
