There are really two reasons why the self-propelled wouldn't work. It could either be the belts on the vacuum cleaner are stretched or broken. The belts on this model control both the self-propelled transmission, as well as the brush roller. Here's a video that shows you how to inspect the roller brush and belts to make sure that they are installed properly and working. Try this repair first, as this is the easier one to fix.
The other problem if the belts are installed properly that would cause the self-propelled wouldn't work would be the self-propelled actuator arm. There is a cable that starts at the handle of the vacuum, and runs all the way down to the floor head of the vacuum that controls the transmission. As you pull backwards on the handle of the vacuum, the cable pulls this actuator arm backwards, which then turns the wheels backwards, and when you push forward it turns the wheels forward.
The problem with the way it's designed however, is that if you pick up the vacuum cleaner by the handle of the machine rather then using the carrying handle on the back of the vacuum, it causes too much tension on the actuator arm, and will cause the cable to rip right out of the arm.
This is a VERY common problem on this model. To check and see if this part is broken on your vacuum, step on the handle release pedal so that the handle is in the vacuuming position, push the pedal a second time so the machine lays flat on the floor.
Now if you look right behind the height adjustment switch, and the rug / floor switch where the floor part meets the upright part, you should see a cable that connects into the actuator arm. Pull up and down on the handle and look for movement. Is the cable loose with only a nut attached to it, or is it resting in the actuator arm?

its the switch. order the switch from the company or your local vac shop. 2 to 4 screws on the handle. then go to were the hand tools are kept, there should be 4 screws. then splice the wires and put on the wire nuts and new switch and your in buiesness. ( check for a clog before repair )
Chris Jones I tried your suggestions and the cable seems to be moving fine.. in my Case it seems to be just the wheels on the bottom of the vacuum as if they are jammed but I dont see anything.. I cant even spin them by hand (I'm assuming I should be able to lol).. I know I really need to clean the bottom of it but I dont see anything jamming the wheels up
I had the same problem with a hoover windtunnel 6200 - u5477-900. I removed the flexible hose from top of the plastic tube running vertically along the right side of the back of the vacuum. When I used a flashlight to look into the plastic tube, I could see a clog at the bottom, where the flexible hose curved frontwards towards the brushes. I then removed the 2 screws holding the vertical plastic tube to the vacuum. When I disconnected the plastic tube from the flexible hose at the bottom, I found a clog of dirt and dog hair. After removing the clog and reassembling, the clean / dirty light now moves back and forth from red to green.
I'm not sure about a 3 month old vac, I'd probably go the warranty route. However, for the older vacs thy start getting false positives. The sensor is simply a microphone hooked to a computer chip detecting sounds of dirt entering the bag.
To rig it to start working, you'll need to remove the tool accessory tray and elbow that enters the back of the vac, and attached to the bag. This will reveal the microphone at the elbow, and wire that runs into the bottom area of the vac. When on, a large amount of air comes from the bottom screw and area where the wires enter. My fix was to clean up the microphone contact points a little bit with a screwdriver, and then leave the vac running while putting in dampering in the hole at the bottom, and around the back of the elbow. Cotton balls and electrical tape at the bottom hole, and napkins around the outside of the elbow (wedged between the back of the vac assembly and elbow did the trick). The schematic for the vac is here: http<colon>//www<dot>vacsrus<dot>com/CartGenie/pg_U6485900<dot>asp Look for micrphone.
I found the following solution on this website. I have searched for hours and finally found this solution, it works! I HAD the same problem after cleaning the filter mentioned below, it is now working like it was new.
***by maverick_bea*** yes this machine has a thermal protector in it to shut off the machine
if it gets to hot, this is normal. if there is no clogs in the hoses or
in the machine then you will need to wash the filter at the top of the
machine. you will have to remove the dirt cup and at the top you should
see a half moon orange, well inside of this piece is the washable
filter, clean and let it dry completly before putting back into
machine. if this gets dirty and has not been cleaned, you can lose alot
of suction. in some cases if this filter is not cleaned it can cause
the machine to overheat so bad that it can damage the motor.
I found this on another site and it worked for me. RonL
Looking at the brush, remove the two screws from the black plate holding the brush. There are two clips that holds this plate once you remove the screws. This should be easy to remove with a flat type screw driver. Now is the tricky part to remove the top cover of the vacuum so you can access the compartment to put the belt on. The whole top part of this vacuum comes off. If you look above the part where black plate was, there are two more clips on the top left and top right hand corner. These two hold one end of the top cover. It is not as simple as pushing the clip to one end to slide out. You have to find a gap between the edge of top cover and bottom structure(right next to each clip) and shove the flat screw driver in and push the top cover away from the bottom structure and push down the top cover. You will notice that there are invisible hinges between the two which locks in the top cover.
Do the same procedure for the bottom right and left edges(right next to each end of the brush) of the vacuum and separate the two(bottom structure and top cover) out using the flat type screw driver..
If a vacuum has not suction then there has to be something plugged up in the port. You will probably have to remove the bottom. Either with a bag or bagless, find the suction port and usually it's plugged with all kinds of stuff. Sometimes if you have access to compressed air you could blow it out from where the bag hooks up or if bagless where it empties into the container. It's not that unusual for it to plug up. My parents have old old old carpet from I think the 70's, (The shag type that you can use a rake with) and there vacuum is always getting plugged up. Good luck.
This is definitely a problem with your belts. This Hoover Windtunnel Self-Propelled models has a poorly designed belt system that frequently goes bad. Most customers will have to replace the belt once every 8-12 months, some even more frequently than that.
There are 2 belts on this machine, and it's recommended that you replace both belts at the same time. If you just replace one of the belts, this will cause the other belt to go bad quicker.
Here's a helpful video that we've recorded that shows you step by step on how to replace these belts, as well as how to do the basic maintenance on the roller brush to prolong the life of the belts as long as possible.

You have to remove the motor cover, There I believe 5 screw, take off the light lens and remove the screw holding the light. It should then pull off. You say you have power to the Vac, but do you have power to the motor. There also is a thermo by the motor, sometimes they open up, then the motor won't run.
