Hi, I am Mike, welcome. I'm reviewing your question.
I don't' think they are related and the water could be from the evaporator drain hose or tube logged up and can usually be unclogged with a little compressed air, no much like 10 psi or so, the water could also be a rain water leak if the floor gets wet when not running the ac and instead after or during a rain storm, especially if you have a sunroof or lights installed on the roof. the blower not working would also not be working when it's on heat and could be several things, such as the blower motor itself going up, which I doubt, cause they usually either work or not and make a noise when the begin to fail like a bearing noise spinning. It could also be a loose electrical connection on anything along that blower motor circuit which includes any switches, resistors, grounds and fuses. I will provide you with the wiring diagram shortly.
I will need to know though, if this is an automatic or manual air conditioning system?
Actually, it's late and I am going to bed, so I'll just give you both diagrams, You might also want to have the trouble codes retrieved from all of the computer modules to see if any refer to that blower motor circuit and/or that blower motor control module.
No leaks when what is not running?
the heater is not working or the blower motor also doesn't work when the controls are on heat?
This diagram may help in locating that evaporator drain hose. http://www.wholesalegmpartsonline.com/showAssembly.aspx?ukey_assembly=375038&ukey_make=1026&ukey_model=14604&modelYear=2007&ukey_category=19473&ukey_driveLine=11477&ukey_trimLevel=14690
