Stereo was okay before, just a crappy, possibly stock, CD & tape deck.
Work done on car was A/C condenser replacement, A/C refrig. fill/conversion. Since this, both decks are DEAD. No power/lights/operation to the deck at all.
My suspicions are a disconnected ground, blown fuse.
Is there anything specific they might have hit/disconnected etc. doing this work? Where can I check the gound(s) for the stereo? Any other ideas?
Thanks.
