Sequoia 2003 power seats don't work.is it fuse or......if fuse where and how I can replace

switch fail --track damage/fail/debris

There is a fuse in the fuse box either under dash or under bonnet and on the back of the actual radio itself!

Sounds like a Controller Issue with the Climate Control. Seeing that you applied power and it worked, then it is not the Motor.

UNLESS you try it on ALL SPEEDS and if it then does not work, you have an Input problem.

If it only works on ONE SPEED, then you have a Resister Issue for the Blower

Find the drivers door module and the memory seat module. All the orange wires should have power to them. If they don't than you need to go back and check the fuses. The LGM/DSM and DDM fuse for sure in the rear fuse block.

Since nothing is working I suspect that the modules may have shut down. Since they communicate with each other it would probably be a good start to scan these with a multi-function scan tool to 1. see if there are codes and clear them and 2. to see if they are still capable of communication.

There will likely be codes stored in every module. Clearing all of the codes would be a good start.

I don't think that there would be a fuse for each window, it could be a wiring problem check the wires on the window switch that isn't working to make sure the problem isn't there also check the wires on the window motor, if you have a test light you may be able to trace where the power is getting to before you replace the window motor,if the power is getting to the window motor you would have to assume the window motor is faulty.....hope this helps......cheers.

I would check the fuse. The fuse is there as a first line of defense. So in theory the fuse chould have blown before any damage could be done to the radio. I would also see if there is a relay for the radio and check that as well.

it probaly needs freon

First make sure that the rear wiper is parked all the way down in the receptacle on the door, if the wiper is not down all the way for some reason the window will lock. Next check the motor itself by removing the rear inner panel and the metal plate, apply power from a 12 volt source directly to the motor, unplug it and ground one side and power to the other, the reverse connections if there is no response from the motor replace it, if the motor works this way a common problem is the back door ECU.

You need to examine/replace the following fuses:
15 amp POWER OUTLET
7.5 amp RAD No. 2
15 amp CIG

Let me know if this helps.

I would check the fuse first, and if that isnt bad, there is a float in the gas tank that sends a message to the gauge to how much gas is in the tank
