Question about 2000 Buick Park Avenue
I have a 2000 Buick Park Ave, the rear defroster doesn't work but the mirrors do heat up so I'm safe to say there's power going to the switch. But I don't have a wiring diagram to see what wire should be live on the relay under the back seat. The relay for the rear window is a 4 prong square block and it can be installed backwards. does it matter wich way it goes?
The common problem with the rear defrost not working on a park ave is the antenna integration modules on the rear c-pillars. This is the way they make the rear defrost and antenna part of the same grid on the rear window. If your external mirrors are heating up, the rear window is getting juice too. They are fed from the same circuit. And yes, the relay does go in a particular way. Compare it to the position of the others nearby and insert with the same orientation.
