This video shows how I repaired the clock in my 2005 Toyota Corolla. These instructions should work for a 2003, 2004, 2005, 2006, 2007, or 2008 Corolla. There is a common problem with the clock in the Toyota Corolla that causes it to stop working intermittently and then eventually not work at all. The problem is caused by the solder on some of the joints on the circuit board. The fix is to touch up those joints with a soldering iron. This video contains instructions for removing the clock, fixing the solder joints, and reinstalling the clock.
