Defogger of my City 2005 has completely died. 3 years ago it started with two circuits not working to all gone bad by now. Went to Honda Workshop but they told me I've to replace the enitre rear windshild for that.

Friends, can you help me get it repaired? Is there a way to do it? I've seen a DIY to repair a few circuits of iDSi but mine is completely gone bad. Also I don't have time to read and do it myself. Also, plz suggest a Electrician/mechanic in Lahore who can repair it.
