System blower operating normally at time of arrival. Inspected unit i itself, and found thermostat wire in bad shape, with a lot of copper exposed. Due to rain last night, the water may have been a conductor of electricity and essentially jumped the r wire to the green wire, causing the blower to work sporadically. Pulled excess wire out of duct cover until I had enough good wire length to connect to the unit, cut off the bad wire, and attached the good wire. Asked tenant to call us back if she had any more problems
