Not sure about that model of 5 series but the 3's used to have trouble with resistor packs dying.
It could also be the control panel.
Its an E39.
When you say control panel what do you mean?
Cheers
The bit on your dash with the buttons on it.
I knew that Silly...
The indicator (graded ) increases but the fan does not start.
sounds like the resistor you mentioned?
To be honest I can't really remember. We had this trouble on an E36 328ci. The resistor pack was replaced which cured one problem but then the control panel had to be replaced for another. They were quite similar to the problem you mention so chances are it could be either (if the 5 you drive utilises resistor packs).
If there's a BMW specialist near you talk to them rather than main dealer. The resistor pack was cheaper than the control panel.

This happened to me a few weeks ago - No fan at all despite what setting the controls were on. Did some research on www.bmw5.co.uk and gathered the problem was the final stager resistor otherwise known as the hedghog resistor. Found this site www.540i6.com/finalstagereplacemen where a guy has posted specific instructions to change the resistor. I bought one - bout £58 quid and changed it myself. Bit awkward to get at, but easy to fit - just plug in and out. Fixed the problem.
