air/heater sounds like an airplane, my car has 147,306 miles. The car was wrecked a year ago not too much body damage, but now if i turn the heat on full blast, it makes a "eerr" sound. I was thinking it was my fan, but im not sure. It also leaks fluid on the driver side floor. I think maybe now its my fan motor and my thermostat. I have never worked on a car in my life, but I have kinda made this my side project lol. i intend on doing the work myself, so any advice would be greatly appreciated. :)

The whirring is probably the blower motor squirrel cage, "usually comes with the motor".

The fluid coming in on the floor may be a couple things.
What does it smell or feel like. IF you use a white paper towel, you may be able to get the color of it.
Are you losing coolant or have any heat loss?

Is the floor always wet or just after rain?

Suggested Repair

The whirring is likely the blower motor squirrel cage, which usually comes with the blower motor. Identify the floor fluid by smell, feel, and color on a white paper towel, and check for coolant loss or reduced heat. Note whether the floor is always wet or only after rain.

Conversation Summary

The owner of a high-mileage Chevrolet reports a loud whirring from the heater fan on high and fluid leaking onto the driver-side floor after a prior wreck. They suspect the fan motor and thermostat. The expert says the noise is probably the blower motor squirrel cage, usually replaced with the motor, and asks about the fluid's smell, feel, and color, coolant or heat loss, and whether the floor is wet only after rain.
