I hate to be anal (but I'm going to do it anyway)!!
In any crosswind - even at 90 degrees - there will always be a headwind component as a result of the fact the aircraft is cocked into wind.
Someone with an FMS or Jepp computer could work out how much it is, but at 35 kts. with a Vref of 130 kts I reckon it'd be 6 kts, give or take, as headwind.
Have a look at your GS relative to your TAS next time you're flying at right angles to a jetstream.
