Windshield defroster, disconnecting

NOTE:

If the windshield forms a crack through a foreign object (e.g. stone impact), disconnect the windshield defroster, so that the crack does not continue.
Control head -E87- does not activate the control module for the windshield defroster -J505- in the operating mode "Econ."
In order that A/C function is not reduced, activation of the windshield defroster control module -J505- should be interrupted until replacement of damaged windshield defroster -Z2-. Therefore, remove connector -A- from control module -B-.
