Subject: Accerssory Receptacle/Cigar Lighter Is Inoperative (Check Aftermarket Device Plug for Short to Ground)


Models: 1995-2000 Passenger Cars and Trucks


Condition:
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.


Figure 1


Cause:
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.


Correction:
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.
Place a piece of tape over the mini fuse terminal temporarily.
Explain to the customer that the fuse for the device must have no exposed terminals, and that finding one would be his responsibility.
Refer the customer to the manufacturer of the aftermarket device for a new plug.


GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
