Heater blower motor
Hello in the FORUM, This question is for anyone who have had problem with the heater blower motor. The motor works fine, the console switch is new, So, Somewhere between the Motor and the console switch lies the problem, I do get a clicking noise under the hood when i put 12 volts to the positive side/terminal of the switch .....Where is my problem, ANYONE??

Does your Corvette have Air Conditioning????
Do you have ANY activity in the blower motor when you use the switch???.....meaning low, med or high speeds???
Do you have a service manual or wiring diagram???
Do you have basic electrical test tools...such as a volt/ohm meter?
I do this for a living on Corvettes every day..so all I am trying to do is help...but I need to know what you have and what is going on so the problem can be found. So please do not take any offense in what I am asking.
I do have to agree...depending on other variables....that the blower relay can be bad...but that usually controls the high speed function...but without knowing what year and other particulars...this is only a very well educated guess.

It sounds like a relay issue. The clicking you hear is the relay.
The wires and connector at the relay have a long history of failure so you might take a hard look at the connector at the relay and make sure all the connections are making good contact.
Here is a simplified schematic to help you.
