89 240 rear defrost grid. Only a few lines at the top actually do anything. Any ideas on the best/ easiest way to fix this? New back window is not an option. Also went to a couple of auto parts store to get a brake light switch for same car, all the aftermarket ones say for a standard car and have bullet connectors. Mine has spade connectors. IPD has MTC for about $6.00 and OE Volvo for over $30. What's up with that?
