Checked the 50amp fuse and thats ok.
Found there is no 12 volts to the connector to the fan just 3.4v at the thin
signal wire.
I tried by putting 12 volts to the fan plug but nothing.
Thank you all in advance.
very hot dave king

That "Thin" wire provides what is known as a modulated pulse signal to the electronic in the fan. Get a scanner that can read BMW code and do a scan of the X5. A bad fan will show up in the DME module.
