93 Mondeo Central Timer Test

Anything on the '93 Mondeo that is timed i.e. Heated rear screen, interior lamp, wipers is controlled by the Central Timer module. To test the functionality of the module you can carry out a Central Timer Self Test.

• Turn the wiper switch to the first position.
• While holding in the heated rear screen switch, turn the ignition on and release the switch
• Each time the heated rear screen switch is press one of the following will occur :- 
• The interior lamp will illuminate.
• The wipers will sweep
• The heated rear screen lamp will illuminate
• The door ajar chime will sound
• The cycle will repeat until the ignition is switch off

If one of the above does not occur then there is a fault in that system. It is very rare for one of these modules to fail.
