Hello
What is the year and the model? Have the battery cables been cleaned and checked to make sure you have a good connection? Has the battery been load tested on a battery tester? Based on all that you say you have a low voltage problem, if the battery hasn't been properly tested do so, any Autozone will do it for free.
I would start with the ignition switch. The horn and interior lights are two different problems. Lets get it started first. The rest points towards the switch. These are easy. remove the steering column bezel. 3 or 4 screws on the bottom. pops off. Two screws to remove the switch. These may be torx screws or bolts so be prepared.
Hello and welcome to FixYa!
It can be a disconnected or loosen battery connectors. As a first course of action, I strongly suggest that you tighten the negative battery connector. Please do check the body ground to the body as well. If possible add more body ground and observe how it goes.
Hope this helps and thank you for using FixYa! Have a good one!

I checked battery and connections and installed a new ignition switch prior to contacting this forum. I bought the car used and although the car fax doesn't list any accidents or other problems, I feel it was at one time involved in a flood, due to the look of rust on the undercarriage and parts of the engine.
I've already replaced the ignition switch, prior to contacting this forum, Under the advise of the professionals at AutoZone and O'reilly's. I believe the car has been involved in a flood although the car fax doesn't list it. It has dirt and sand in unusual places in the engine and undercarrage.
'It's a 97 ford taurus, purchased used has "67500 original miles". Battery cables have been cleaned, checked and the battery has been tested to be good. However, you make it sound as though the battery may not be putting out enough juice, and if that's correct, the voltage could be causing the problems. Is this correct? If so, would that make the fuel guage and the speedometer operate improperly?
