It sounds like you don't have any blower fan operation, If I read correctly the large a/c line is cold and I would suspect the other smaller a/c line is warm or hot. Those have a lot of problems with the blower fans and the blower control module.

You could remove the right lower dash black panel so we can do some testing / inspection at the blower motor and control module. Do you have a volt meter, or at least a test light?

Check fuse # ***** in the under hood box. it is a 30 amp fuse for the blower motor.

Also check the heater a/c fuse in the left side inside fuse box 25 amp to see if it is ok

Did you find any issues with the fuses, were you able to check the blower motor and control module connectors for any issues?
