Yesterday I repaired the electronic clock on the 2006 Toyota Corolla LE. These are known to go out after many years, 15 years, due to brittle solder joints. Mine would go from full black to working to very dim. Needed to be fixed. The factory part is a $246 item my price. I decided to attempt a repair of the old one.

You remove the shifter cover by using a thin screwdriver or trim tool and gently pop up the plastic. Had to shift transmission nto neutral to remove it.

The pull off the middle heater knob which is fan speed, and remove Phillips had screw underneath. Near the electrical connectors under the drawers is a metal ledge, pull towards you and whole console comes out. Then push both ends of clock from front it just pops out. It is a friction fit. Unplug the electrical connector at back of clock.

I then took it to the soldering station and opened it up. There are 5 SMD resistors on the printed circuit board that need to be resoldered. If you are not comfortable with SMD soldering I would not try it. You need a temp controlled soldering station not your $25 Weller iron. I resoldered all 5 using narrowest solder tip with a bit of extra thin gauge solder to float it in all 10 solder joints.
Put it all back together and reset the time. Works like brand new and brighter than ever.

with my ham fisted approach I managed to break off one of the ears of the top drawer and cemented it back on with Tiger Bond and letting the joint cure another day before reinstalling the drawer.
