Hi, I'm CamI will answer your question quickly but we may need to discuss this further. Please reply to continue the discussion.
There is another fuse the CIGAR fuse. THat is in the underhood fuse block as well. Check that fuse and see.
The cigar fuse is circled in red.
I've checked and replaced the fuses labeled "AUX PWR" (20 amp) and "CIG LTR" (15 amp) fuses in the UNDERHOOD Fuse Block. My cigarette lighter is working fine. I've also checked the fuse labeled "AUX PWR 2" in the Instrument Panel fuse block.
I wanted to know if there was a hidden or additional "In-line" fuse that supports the "Auxiliary Power Outlet" that is mounted just to the left of the Cigarette Lighter outlet.
If there is an in-line fuse that needs to be checked or if I need to get to the back of the Auxiliary Power Outlet to repair or replace it, what panels need to be removed and the process associated with that.
No sir, no hidden or inline fuses at all, just the ones that you found on that fuse block, CIGAR, AUX 1 and 2. DO those have power with a test light?
Are you testing across the 2 parts of the fuse?
Ok, lets try it this way. put one lead of the meter to ground and then test each fuse leg.
Ok, that is expected and proper. Only one leg will have power and testing over the 2 legs like that will not give good results if there is anything plugged into the outlets. Can you repeat that test for the CIGAR, and both AUX fuses?
Okay, I measure the voltage on each leg of the other two items. I connected the negative probe again to the negative side of the battery and touched each leg of "CIG LTR" fuse location. One side had a voltage of 0.03 VDC and the other had a voltage of 12.7 VDC.
The measure values of the "AUX PWR 2" fuse location were also 12.7 VDC on one side and 0.03VDC on the other.
Anticipating your next move, I reinstalled all of the fuses in their proper location. I then measure the voltage from the negative side of the battery to the outer metallic portion of the Cigarette Lighter Outlet. The voltage there was 0.03VDC. I then measured the voltage from the negative side of the battery to the center back part of the cigarette lighter outlet. It read 12.7 VDC.
I measured the voltage from the negative side of the battery to the Rear Auxiliary Outlet (AUX PWR 2) circuit in the cargo area of the vehicle. Its readings were similar to the Cigarette lighter readings... 0.03VDC on the outer metallic shell and +12.7VDC on the rear metallic portion.
Finally I measured these values for the faulty Auxiliary Power Outlet next to the Cigarette Lighter. It read 0.03VDC for both the outer metallic shell and the rear center metallic portion verifying that it was not getting power from the battery on one side of this circuit.
What do I do next?
Ok, which location exactly is the faulty plug at?
PS, GREAT DIAGNOSIS!! I wish all my customers went this extra mile.
That seems too wide, but there are 2 and about 1/8 square.
Either way, that pushes out and the housing or plastic stays, and the metal pulls. Try again but slip a small flat blade screw driver behind the lip to start pulling the insert or metal out.
Yes I suspect the outlet. I see that often. They are cheap from GM, 10 or so at the most. Then they just push in.
The tool from GM for removing it makes it easy, it is a T that is the perfect size.
That is what I do best.
