Left vent (passenger) - hot. Middle left vent - not blowing anything. Middle right drivers vent - blows with under dash control knob correctly but only cold.
Where to start looking? (bear in mind I'll have the whole dash of in November)
Thanks. Ironically, since that post, my passenger fan has jammed - buzzing and blowing the fuse, and I've read that the drivers fan is cold only anyhow!
