Road defroster INOP

Rear defroster hasn't work after a hail storm or maybe even before that. When I picked up the T, 2 years ago now. The driver side connector to the window wasn't attached.

I've scuffed up the two connecting points and reattached using some specific defroster adhesive. The light illuminates when turning on the defroster.

Continuity test to the relay shows that its in good working order and the fues is just fine. What eles should I look into on fixing this fault?

Thank you.

Check for voltage on both sides of the defroster to ground, the conductive adhesive may not be working correctly.

Another issue might be the connector from the harness to the defroster wires, if there is one. The SUV H3 has one in the rear door that connects both the defroster wires and the 3rd brake light wires to the harness. On my red H3 one side of the connector was going bad and melting the housing and lost contact in the terminals intermittently. I fixed it by removing the defroster wires from the connector on both sides and crimping on new spade connectors.

Thanks for the info!!! I'll get on it in the morning and post up the results. I'm sure the issue is somewhere on the window end.
