Several months ago, using a crappy 12V plug-in inflator the inflator shorted out. I didn't immediately notice that the dash power adapter, below the cigarette lighter went dead too.
I've checked the specific dash 15V fuse with a VOH meter. It tested fine. With the ignition on I checked the cigarette lighter and got 12V, when I tried the power adapter there was no response. I also tried a known good (tested) power cable plugged into the power adapter but there was no meter response.
On visual exam I noticed that the center contact of the power adapter wasn't very substantial; also that the adapter cylindrical shell pulled about half way out of the housing. Perhaps an open circuit at the adapter?
Is there any type of fusible link between the adapter and the fuse? How big a deal is it to change out the adapter unit? Do these units simply rotate and pull out or is it necessary to disassembly part of the dash board? Any additional troubleshooting advice would be appreciated.
