My car has does not start all the time. This happend about once every 2 days for about 3 months. Today it would not start at all. When I turned it on it buzzed (never heard before) and dinged (lk I left keys in there) and gauges were going crazy. Then with no key in ignition and a/c off, the fan was going on and off. I jump started it and there was smoke coming from either battery or electrical box, not sure. But it started and ran w/h clicking noise and service engine light now on. Fuel gauge is stuck pointed down. Also notices clicking noise coming from electrical box. I took to Sears auto and they would touch it. Thank you!

Okay. I can understand why sears wanted to run (LOL). The first thing I recommend is to check where the clicking noise is coming from. If it is the power distribution box under the hood, it could be something as simple as a relay that fried. Check for evidence of anything that has overheated (since you saw smoke).

Let me know what you find with that. As far as the inst cluster, I have to be honest, they have a history of going bad and needing replaced. However, since the problems happened at the same time, it still may be good.

Check what I mentioned and let me know what you find.
