Climate Control Blower

Need help from the gurus: I replaced the blower motor regulator about a month ago, restoring normal fan range. I didn't have the ability to solder connections so I was less than excited about the connections I made twisting the wires & using electrical tape.
Today my fan quit working at one point on start-up. Later in the day I tried it again & it worked normally, next start-up no fan again. I checked the climate codes, fan not blowing, observing #10 for the blower control voltage showing a range of .8v to 6v dependent upon fan speed selected.
Should I re-check the wiring? Since the voltage is showing without getting action, could it be the fan or perhaps the regulator malfunctioning?
Thanks for sinking your brains on this one?!!

Get some butt splices and a good crimper and do those connections properly. Solder isn't appropriate. Neither is simply twisting the wires together.
