I'll tell it's not the blower motor , it's the blower motor control processor . It's mounted to the blower motor case or heater box .

Replace the timming chain, gears, and magnet. With that cat getting that hot it has to be out of time. When the cam sensor picks up no signal, ecu can't control timming and reverts back to a preset,fixed base # .

Sounds like something is drawing too much current for the resistor. Maybe blower motor going bad....

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

Your blower motor is starting to fail, and needs replaced to fix this. I have this problem on one of my vehicles that is not used often, but in my case the fan will work on the medium setting and function without blowing the fuse, so to save money I hae not replaced mine yet. I yous does nt work on any setting you'll need a new one.

The resistors are located in the firewall just above the blower motor. they have a heavier gadge wire going to it. As for the water if it is not antifreeze then you have a leak in your cowl area by the lower windshield. I ran in to this problem on several gm cars such as yours it can be deficult to find good luck
