The car was working fine, I parked it on Friday and went to start on Saturday and nothing. No radio, lights, power windows, no cranking. I thought the battery was dead so I tried to jump the car and still the same thing. FYI: I had a new fuel pump installed 2 months ago.

Thanks

No, is there some type of master fuse I am looking for?

Get that altenator tested out.

Check your owners manual for the fuses under there. Tech Info has links to the online versions.

That'* basically the first play all the lectricl in your car goes before being distributed elsewhere. Also, check the connections there. I had a Series I LeSabre where the connections on the relay center had corroded a bit, and it would do just what you mentioned, no juice to nothin'!!!

The alternator has absolutely no effect on starting whatsoever. Check all your fuses in the car and under the hood. If you find nothing, and are still unable to start or power up, clean both ends of each battery cable. This means at the alt, starter, ground locations, etc. Remove them all, clean with a wire brush, clean the mating surfaces, and reassemble.

I put a new battery in and it started right up. I had a new battery installed 1 year ago?? Now the strange part, the HVAC runs with the keys out of the ignition. I can turn the HVAC on and off with the car off. I’m sure that’* what killed the battery the night before.


P.*. All fuses look good!

Thanks for the help!

I've seen this 2 or 3 times here in the last year. I think if the HVAC fans run after shutoff it'* a bad resistor pack? Working from memory here.
