Question about 1998 Buick Park Avenue
Where is the interior fuse panel for the rear defroster in a 199
8 buick park avenue ultra?
I just accessed mine. It is under the rear seat. You just lift up on the seat, and it pops right out. If you are having problems with the rear defroster, it could very likely be the control module. This is a combination module which the rear antenna, and the defroster grid plugs in to.
When mine went out I smelled a "burnt wire" smell, then it went out.
To access the module, sit in the back seat, drivers side. There is a trim panel that will be by your left ear as you are looking forward. It is the panel that flares down from the ceiling to the rear deck. Gently pull at the edge of this panel, working around the edges, and the small strip which continues over the top of the door.
The seatbelt goes through this panel, so it will be hanging from the seatbelt at this point. There is a ~3" square, black module with the defroster input and output wires, and the antenna wire plugged into it.
You just unplug the wires, pull the one mounting screw, and voila!
On mine the module was obviously melted, as was the wire going into it. I got the replacement from a salvage yard, as the new one was over $50, and the replacement wire was $18. The salvage yard was unable to look it up, so I had to go out to the yard with them and pull it myself. The final cost was $17 (they tried to charge me $40, and I told them I could get it online for that, and they dropped the price).
You can use a crimp on **** connector to put in the replacement wire, but because of the heat in that area I chose to solder the wires together.
BTW, this module fits a wide range of Buicks, and full size Olds.
Hope this helps.
