Demister switch stuck
The dash rear window demister switch on my Volvo 740GL (1985) has got stuck in the ON position, and the demister is still working. Do I need to change the control relay switch? If so, where do I find the relay to replace it?

Welcome to Matthew's Volvo Site.
Attached is a diagram of the fuse/relay board for the '85 740. This is behind the front ashtray.
However, if the switch is stuck replacing the relay will not solve the problem. You need to get the switch working or replace it.
