The defroster only works occasionally, and only for a minute before stopping. It appears there is a short somewhere. My mechanic can not make heads or tails of the sea of wires beneath the dashboard. what...
During the restoration of our '92 Lesabre, we had an auto glass guy come out to remove & hopefully replace the same glass in the rear window section(the window trim had disintegrated and we bought new stuff to replace it with, but it wouldn't fit unless the window was removed).
What was discovered when the window was removed... was that the defroster interface on the sides of the glass was basically disconnected from the glass: the solder contact patch where the power & ground wires interfaced with the defrosting wires was corroded. It fell off once it was pulled on. In our case we had the whole rear window replaced.
What may be possible for you to do is pull back/off the rear pillar trim that covers the defrost wire & connectors and re-melt the solder with a 80-150 watt soldering iron(assuming that is where the problem is). I suppose, before buying and/or firing up the soldering iron, get the rear trim that covers the left & right edges of the rear-glass removed to find out IF the connectors & the long vertical strip they attach to are indeed attached to or detached from the glass. Oh duh, the vertical strip that the power wires connect to on either side run from top to bottom of the defroster array and are the portions that solder to the glass.
If it results in soldering, I'd suggest you use either a resin/flux core electrical solder or use a flux paste brushed over the solder contact areas & use solid electrical solder.
If I wasn't so busy with other parts of the car I would have gone after the soldering myself... but being as pre-occupied as I was that's why we opted to have the whole window(which includes the defrosting array & connectors) replaced.
I hope things work out for you regarding this... shoot me back if you need any other info/follow-up.
