Hello I will help you with your question,

Bulletin No.: 99-08-45-005
Date: November, 1999
Subject: Accessory Receptacle/Cigar Lighter is Inoperative (Check Aftermarket Device Plug for Short to Ground)
Models: 1995-2000 Passenger Cars and Trucks
Some customers may comment that the cigar lighter or the accessory receptacle is inoperative; or that the internal fuse (within the plug on an aftermarket device), blows intermittently.
Certain aftermarket devices have a newly designed power plug with an internal mini fuse. The mini fuse may have an external terminal (which may be used to externally check the fuse). If the mini fuse external test terminal is not recessed into the mini fuse body, it may come in contact with the shell of the vehicle receptacle and cause the fuse (of either the vehicle or the aftermarket device), to blow intermittently.
Test the aftermarket device plug for short to ground. The following step may be performed at the customer's expense. As this is not a defect in material, design or workmanship of the vehicle, it would be the owner's responsibility.
If your adapter is OK maybe the fuse is blown? It is the blue 15A fuse in the underdash panel in location 9B
If you need to remove the lighter assembly it self the IP knee bolster shown in #4 will have to be removed
If the fuse is blown it is likely one of your adapters is shorting in the socket
