Blowing air out of the right side? As in blowing air out of the right side of the hood? If its a light stream of warm coming out of the vent in the hood that's normal, its exhaust air from the motor. Now, clogs can occur at the outlet from the fan chamber. Remove the bag from the base of the machine via two screws. See if that area is clear and the tube going up into the bag unit is clear as well. Now, if the fan chamber is clear, inspect the fan for breaks or missing blades.
My solution is one that only works if the vacuum is a spare... To get mad at it and throw it in the garbage...
My thought though on what the problem actually was... Seeing as where the vacuum came from and what the problem was, that it was run with the fan broken causing more damage to the motor and therefore making it impossible to fix with just a fan. I would suggest that if your vacuum sounds different than it has before, stop running it and see if there's something you can do to fix it and if not then don't keep running it. Coins are the main problem with a broken fan and are not made to be sucked up by a vacuum cleaner.
You might want to check the brushroll. It may need to be replaced. The brushroll end caps on your model should come off easily and if there is a collection of hair, etc under them and you can clean it out, do so. If it is impossible to clean out, you must replace the brush. You can get one at any Eureka/Sanitaire dealer or warranty station. If you have a model 1934, you can upgrade to a better metal brushroll which won't give you as much trouble.

Remove the base plate and remove the wheels and axle. Remove the hair and threads that was causing the wheel to lock up. You will need to use a box cutter or similar to remove the debris. Add a couple of drops of light machine oil and reassemble.

This can be because you need to adjust the tension or probably the pulley is no longer aligned. So find out if the shaft is no longer straight also if the belt requires tension.
Nothing you have described should cause it to fail. Claim on the one year warranty irrespective of how long you have had it. What happens if you remove the hoses and turn the machine on? Does it suck from the hole in the body where the hose attaches? If it doesn't then the disc that is attached to the motor has sheared off the motor spindle. Was the stone in the bag, or did it punch a hole in the bag and meet the motor?

Locate the filter compartment on the vacuum. It is usually located under the dirt cup or canister.
Remove the filter compartment cover by pressing the latch or pressing the button and pulling the cover off.
Take the old filter out of the compartment and discard it.
Place the new filter into the compartment, making sure it is properly seated.
Replace the filter compartment cover by aligning it with the vacuum and pressing it into place.
Make sure to properly maintain and replace the filter as recommended in the owner's manual to ensure optimal performance of your Eureka 4335 DX vacuum.
