Hi, here is a walkthrough on how to get to that part here. Steps 1 - 14 on how to access it, you will need to take apart the housing to get at it. If you need a new switch you can find that here. Rainbow did redesign this switch, so you will need to look at the wiring diagram if you are installing a new switch.

SOURCE: Power Switch
This is not that hard:
1. - remove gasket (it is glued so you may end up damaging it)
2. - remove 4 screws holding baffle
3. - under it you will see 4 more screws holding cap
4. - Four more screws and you will remove cap cover
5. - cut the cable tie, make a note how wires are connected, use flat screw driver to press on the latches holding the switch in while pushing onto the switch OUT. Tension will not let the latches pop back in.
6. - reassemble in the reverse order.
Switch - if you have old style switch installed you will need to push something into each hole next to the wires to release them. There is a cooper lip in each hole that you have to bend a bit to release each wire. Installing new style switch (with 4 wires) - attach one power cord wire to one blue switch wire and another to another blue switch wire. Attach one motor and one power nozzle cord receptacle wire to one black and another pair to another black wire.
Gasket - use weatherstripping glue to glue motor gasket back (you can get some in almost any automotive store)

No diagrams - sorry. It is Rexair, Inc. intellectual property and we can not use them...

SOURCE: motor won't start
Most times this will be caused by one of 3 items, the cord, the switch or the carbon brushes in the motor. Inspect the plug area on the cord for strain twist it gently and look to see if the cord appears a bit white where it meets the plug or if the cord appears crushed just before the plug.
Also inspect where the cord meets the body of the vac for the same signs of wear or any locations where it may have been caught in the power head , etc.
If you have test meter, check for resistance change at the plug while twisting and finally try the same twisting with the vac plugged in if necessary but keep your fingers back from the plug in case the cord blows... gently twist and pull slightly to see if the motor continues to run.
Most often when a switch fails it just dies and doesn't become intermitant... so with a meter it will generally test good or bad , nothing else..
Sometimes on a well worn vac when the motor doesn't start the carbon brushes in the motor have worn down. A heavy duty motor such as the Rexair can often be rebuilt if brushes are required.
If you turn the machine on and bump or jolt the side of the body as if to spin it, you can often "trick " the motor into starting. If this happens it is most likely a carbon brush issue , if not time for a new motor.
Rainbow/Rexair machines have a fairly good motor however because of how they run drawing moist air through they often rust as they age. This is a tedius rebuild and best left to a pro shop with parts on hand if requiring brushes. Most shops will simpley scrap a worn motor if rusty and replace it completely.
Before you spend big $ on a repair or replacement....
One last thing....... pull the exhaust cap at the back of the vac. You will seen fine powder dust and residue.Wipe your finger across it. This is what the Rexair releases into your home each time it runs, but you don't smell it because it comes out in the form of humidity...like after a spring rain.
That same humidity is rusting your motor gradually year by year. Although this motor has a long life span, consider that you have been breathing dirty humidity as it runs. If you put orange drink crystals in the water bucket and run the vac, the exhaust air would smell like orange juice,... so what is in the tank comes out in the air, including your dirty water.
Most Rexair owners buy thinking they are helping to reduce allergins.. yet what is on that exhaust plug proves otherwise. If your home is essentially carpet free and you are vigilant maintaining and rinsing the bucket, you might consider rebuilding this vac.. Otherwise consider a good High end European vac like a SEBO,MIELE, Nilfisk etc for better filtration and reliability

Invert the vacuum cleaner without the water tray installed. With the machine unplugged, give the separator a spin clockwise. If it spins easily, this is a good sign. If the bearings are good on an SE, you should hear the faintest of rapid clicking sounds as you spin the motor. This is the sound of the brushes as the commutator segments pass under them. The brushes on SEs will sometimes hang up and not make proper contact; they are too precise a fit in their holders and the carbon dust they generate plus a tiny bit of moisture will cause them not to extend as they wear. When this happens, the brush tension spring overheats, relaxes, and it's time for new brushes and a service. Anyway, if you determine that the motor is turning smoothly (resistance or binding indicates bad bearings), install the water tray dry, plug the vac in, switch on, and give it a couple of bi__ch slaps with the palm of your hand on the side of the vac near the top. This can sometimes free up a stuck brush but the effect is likely not to last. It will, however, give indication of whether the machine might run or not after a fairly cheap repair (under 100 dollars).
