Just bought used 2003 Camry LE. Both rear windows dont' go down. Tried using master switch and also individual switches - no avail. Also made sure child safety lock was disengaged. If it's wiring or frozen motor or whatever, is this expensive to fix?

try changing the brake switch in the floor behind brake pedal.... pedal activates in when used, sending power to brake lights

Absolutely! The rear switch gets its power from the driver's switch.

MAKE SURE MASTER WINDOW SWITCH NOT IN LOCK OUT POSITION.THATS A SAFETY FEATURE TO KEEP CHILDREN FROM OPEN THE WINDOW AND FALL OUT THE CAR.YOU COULD ALSO HAVE BAD POWER WINDOW RELAYS.

depends if its the master window switch next to the driver side door or passenger or rear doors. these are available in the market . you might need to check the window motor individually also. also the fuses

Did you replace the master switch?It will be the main switch,the master on the drivers control.

Have you tried replacing the master switch in the drivers door?
Toyota switches can be dismantled ( carefully ) and the usual problem is dirty contacts.
When you dismantle the switches use a small flat blade screwdriver and do the job in a large clean area where you can find small springs and ballbearings that will fire everywhere if let them.
Happy hunting, Marshall

Please be more specific. Do the windows go down from their respective window control?? If the do then you may have a faulty master switch or faulty wiring damaging the master switch.

the master switch on the left front door hold the keys to all. supply your own power the the switch with like a battery from a power drill to see if its the switch in the master assembly.

No.The drivers master power switch is probably bad.YOu will have to perform a test on the three other switches on the master. Check for power and ground when you push each putton.If the master switch fails the test you need a new master switch.

You might have a bad master switch. Generally, if a window, other than the drivers door, doesnt work at all from the mnaster switch, but does from the individual door switch, its usually a bad master.
