Nissan Repair Questions? Ask a Mechanic for Answers ASAP
This is a faulty fan control amp, also know as the VBC or resistor.
What happens here is when it fails on speed 1 the a/c signal stick kicks on the compressor, but since the compressor signal feeds through speed one when it fails there it causes you to lose the signal at all higher speeds. So the fan will come on, but the compressor is no longer engaged.
I probably see this same scenario about once a month in the summer.
