CD player doesn't work...

Kerry, you can't just disconnect the battery to fix things. Yes it clears the code from the computer memory, but can do damage.

You need an auto electrician with a pro grade scan took computer to read the Diagnostic Trouble Codes and the codes tell you the fix.

It is a known issue

Hi i never worked on it but i would try to Dryglide special product easy up open and close windows and so spry on the edges and see maybe the mechanism is going stiff and force to open u buy Dryglide from Repco good luck

you might of press it to hard when that happens just touch the switch the opposite way,sometime the switch get stuck

My DVD in my 2003 Toyota sequoia DVD player not work

Hi, there is only one relay for all of the windows, so that is not the problem. The likely problem is the switch. I recommend you test the switch using an ohmmeter.
In the case of the door lock, that problem may be a failed lock motor. I recommend you apply power directly to the lock motor to see if it works. If it does, check the switch. If not, replace the motor.

I had this happen in my old dodge stratus. My trick to remove cd's was when you stopped or parked the car turn vehicle off and hit the eject button and it will usually eject the disc. remove all discs and then install them again when car is parked and not moving as vibration and bumps while driving can sometimes miss align the disc in the player. Sometimes when the stereo didn't work at all I disconnected the battery and it would reset and work. If this doesn't work it may be broken. Good Luck.

the cd player and radio should be on the same system or as a whole, it should all be not working, there may have been a short inside the cd player, check all the fuses in the fuse box look for 10amp and 15 amps usually. being a newer car it is odd. you may need to take it in to toyota for a diagnostic check. good thing about the electrics in cars these days is their computers tell you everything.

Most likely your idle speed is too low due to dirt on throttle plates and IAC valve. cleaning these items usually restores normal idle operation.

If the radio works but the CD player doesn't it's something internal to the unit. The radio and CD player get their power source from the same wire that goes into the unit.

toyota radios stink,, need to take out radio internal problem end to radio store to send to radio repair co
