Note: after pulling fuse I started the truck, nothing improved. Turned off the radio, shut off. Turned the key on, some wizzing and a click or two then came out the vent. Started the truck back to deforst, repeated shutting off, key on for over a minute, it went back to the vent, left it for maybe another minute, started it...seems to be working. Thanks Ohio!!

Try this. make sure you turn off the a/c before doing the reset.
see if this works for you
remove hvac/ecas fuse in underhood fuse box for 10 seconds, re install and start truck. turn on the hvac and let it do it's thing, it is supposed to recalibrate after 40 seconds. good luck

I too am stuck on Defrost, truck had the battery disconnected for hot AZ summer months.
Any relays or things to pull out in that big electric box under the hood, I disconnected it again.
Any help appreciated!!!
