OK, if it is a short in the wiring, why would the blower operate on high but not the other speeds? Is the high speed operation on an entirely separate wire. Does the resistor problem ever correct itself?
We'll be taking the truck out of town in a couple of days and I don't have time to get it back to the dealer. We are headed north and I for sure want the fan to be operating. If problem is the resistor which I think it is, will it continue to operate on "high" indefinitely or at least until I can get the truck in to have it checked out.
Thanks for any suggestions.

First of all from what I've read, the High fan speed doesn't go through the resistor. No need to slow the fan down at this speed thus no need for the resistor. In which case, it shouldn't go out on you.
Second, if you followed some of the links that were in my link, you would have been led here:
HVAC blower motor resistor replacement - Toyota Forums :: Toyota Nation
The person that did the write-up on replacing the resistor mentioned that his symptoms were first intermittent. Later the low and medium speeds went out completely. Sounds like you're at the intermittent stage.
So, read this writeup and get yourself the part. Easy to do yourself at $28-$38! The pictures in this writeup are well documented.
