Check that the "Rear windshield defroster" relay 2/82 is correctly installed.
Check the rear electronic module connector and relay terminal 2/82. Check for contact resistance and oxidation. Check for loose connections.
Check the cable between main fuse 11E/5 and the relay for" Rear demist" terminal 2/82#5.
Check the cable between main fuse 11D/5 and "Rear windshield defroster" relay 2/82 terminal #1. Check the cable between rear electronic module terminal #D1 (#B01) and "Rear windshield defroster" relay 2/82 terminal #2. Check these cables for an intermittent short-circuit to ground and an intermittent open-circuit.
