My son's 2006 G35 air works great when it comes on, same with the heat,
but it takes forever for it to start blowing and sometimes it never starts. It
was taking about 10 mins the beginning of the summer and now it's hit or
miss. Once it comes on it works great, turn car off get back in and same
thing, won't come back on immediately. We changed relay switch and didn't
help. What else could it be?
