AC high blow problem

:( : my 1995 Corvette suddenly stopped blowing on the high blow. The Auto setting shows a 10 speed but even that isn't blowing hard. The recirc is the same also. Is this a relay, module, or is the controller going out. I have one but trying to sort out the solution before I start removing plastic. I also checked for a cabin air filter and it doesn't have one. Am I in the right direction or not.

Ok, if everything is normal in the lo M1, M2 positions, but no blow in the high, it should be the "Blower Motor Relay, High".

Everything OK in m1, m2. Recirc and Auto the same intensity. Showing 10 velocity in the auto mode on both settings recirc and auto but the same air or should I say the rapid cooldown is not functioning. I suppose that is the relay just fwd of the motor housing frt of car? I even changed the motor so it's weeks old.

I show two wires coming from the blower motor. One is black and goes to a ground, and the other goes directly to the relay. Looks like it may be purple.

I appreciate the help. I have checked all that I knew about but this one had me going. SOme said there was a high blow relay which I could not find. Another said it was the climate control which I changed. The next person said to change the main control box whic I was ready to do this weekend. I will check for the relay and let ya know the outcome. Thanks again.
