electrical gremlins?

I have a 2005 TJ, 4.0L, six speed, A/C. Here is my problem. The wife was driving home from work, about 30 miles and stopped for a soda, about five minutes. When she put in the key and turned it all she got was a bunch of clicking in the fuse/relay box and from under the dash. Also the gauges are bouncing. Starter would not turn. Headlights come on as well as four-ways. The horn barely makes any noise. When I arrived approximately 45 mins later I could feel the HBL relay spinning. I searched for broken wires, nothing. Towed it home. Replaced HBL relay, same problems. Disconnected battery (zero corrosion on terminals) gauges returned to normal. I read some previous posts on this site and tried replacing the Battery Temperature Sensor, no luck. Any help would be greatly appreciated. Thanks.

Sounds like a battery problem to me, I'd have it load tested. Batteries often go dead very suddenly, especially in the heat like you have there in Arizona right now. Even if jump started, it won't run well for long once the jump battery is disconnected if the battery is dead or nearly dead.

One thing to try to help isolate it down to a bad battery or something else. Turn the headlights on. If they continue to shine at full brightness even when you try to start the engine, it's not the battery. If the headlights go on but dim/go out when you try to start the battery, the battery is either almost dead or you have a weak connection to one of the battery posts... even though they appear to be clean.

When you have a choice, buy American.

I agree with battery. With how hot it is here in AZ battery life dwindles down to about 18 month average.

Same thing happened to mine. Guages would jump even when the keys were sitting on the seat. Replaced battery, everythings fine now.

I agree that it's the battery. The clicking is probably the starter motor trying to work but not enough power.
