Default A/C will not blow at all please help

2003 Silverado I have always done my own repairs, however this one has stumped me. About six months ago my ac would only work on the highest setting as of 2 weeks ago it completely stopped working it won't blow at all and makes a click noise when turned on I have a 10 month old and southeast Texas summers are HOT any help would be great

Reading what you posted, my guess is blower motor.

Reading what you posted my guess is you are low on freon OR your climate control unit went kaput. That explains why it was running on HIGH only before, and don't run at all.

Check the resistor for the motor. It controls the speed of the motor and if it is bad the motor will not turn at all.

FWIW, my experience has been that if resistor is bad, the fan motor could also be bad, causing the resistor to fail. If replacing resistor gets it going, consider replacing fan motor also.
