The heater/ac fan only works in the high position of the switch - is the switch bad or is the fan bad?

This is actually a follow-on to previous post of same vehicle dealing with AC compressor pump - your advice there was spot on and AC blows nice cold air now - now I need to fix blower motor issue.

thanks for this great service!

With the fan running it is ok, would check the blower resistor and the high blower relay. Both are under the dash. The blower resistor is on the right side of the heater housing. The high blower relay is on top of the a/c case.
