1998 528i 5 speed

207000 miles. Just got the car and going through the cooling system,
etc.
Metal impeller water pump
New fan clutch
New coolant switch (the one in the radiator)
If I jump the fan over (center prong to one side) the fan works. A/C
on or not. New switch. No auxillary fan, even when a/c is turned on,
car up to temp, etc. Fuses look good and since I can jump one side of
the connector at the radiator switch I assume the relay is good?

Ideas?

Thanks

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.
