I have a 2009 nissan sentra. when you turn on the heat it makes loud noises like a tank. took it in and they stated that leaves had gotten into the heater motor and that was not covered on warranty as it is a nature problem. I have driven for over 35yrs and many different vehicles and have never heard of this. i park my car in a garage and not exposed to leaves and debris and now I have a $700 bill to clean the leaves . isnt this a nissan vehicle problem in the way they made it?

You mention loud noises after installing the blower motor, I would check to see if the loud noises came from the fan not being properly installed or loose, possibly something interfering with the rotation. If you find that you probably can replace the fuse and reinstall everything as it should be.

You could just plug the blower motor in without installing it to test it. If it doesn't blow the fuse again, fix the obstruction/alignment and you should be good.

Seatbelt or radio code?

If the blower motor is noisy, the bearing may be getting bad inside the blower. This will require replacement of the blower motor unit. In some cases, foreign objects can fall into the motor casing assembly also making a noise. The motor will need to be removed for inspection

That noise is likely a bad bearing from running it out of oil.

That loud humming noise you are hearing is the wheel bearing. After hitting the curb the bearing took a hit and became a little wobbly and over time the grease has seeped out and started causing the humming.So just replace the wheel bearing and anything else that might be loose or damaged like the tie rod and ball joints. if those issues are not corrected it might happen again down the road. good luck and glad to shed some light on your issue

You may need to check the cooling fan and also get the dryer check by Aircon mechanic.
Faulty cooling fan destroy dryer. Just an advise

It could be a broken Oil Pump, Is there oil in the engine or when you hit the pothole you could have hit the Exhaust Pipe and broke the pipe causing a Exhaust Leak.
