The tint on the back window of my new-to-me C32 needs replacing. Also, several of the lines in the rear defroster obviously do not heat. I am aware that minor opens in the defroster lines can be repaired, but I am wondering if it is worth it to pay to have the rear tint professionally removed and then pay to have the defroster repaired, or will it be cheaper to just have the rear glass replaced and new tint applied. Anybody have a success (or horror) story containing these elements? Thanx!
