Radio wont work in my cadillac deville nor cd player or cassette player but cig lighter does and clockdoes

SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

SOURCE: radio/cd player stopped working after battery replaced

Had battery replaced on 2005 DTS and afterward the radio/NAV/On-Star would not work.(Totally dead) The dealer who installed could not locate problem. (No GM dealer in Amador County, CA). I read several forums citing this/similar problems. I checked the three fuses labelled "radio, audio, NAV" by pulling, checking and reinstalling (all three were good). When I then restarted the car, everything was once again working! Poor connection? Corroded contacts? Some mysterious computer glitch? Who knows?
