Guys -
I know it's a long shot, but I'll ask anyway.

2009 Expy, with dual zone. Rear zone works fine, hot and cold. Front doesn't blow on any speed, auto or manual. I've checked all the applicable fuses I can think of, both inside and out. This happened about a month ago, and after pulling and re-seating the fuses, it did start to work again (magically). This time, no such luck.

I understand there to be a resistor involved - but this is largely a problem when you have certain fan speeds but not the others. Doesn't sound like my issue.

From a motor perspective, I don't believe I have a bad motor - never heard any dying noises or issues with it before.

Just from my days of troubleshooting things like this, I'd suspect a relay of some sort. Can anyone point me to it's location - or any other suggestions to try?

Thanks for any help.
