Weird issue. Trying to make sense of what happened

You have a warranty. Take it to the dealer. Or find a copy of the factory service manual wiring diagrams and pin out the circut. Then back probe for power. Could even be a loose ground somewhere.

The trouble is if the issue is intermittent it will invariable work great when the dealer inspects it.

My car recently had a battery fail. Before that, the cig lighter and radio were intermittent maybe twice in several months. I've no way of knowing if that's related to the batt but before this thread I would have not thought so.

Any aftermarket electrical parts installed? Sounds like someone has been playing with the electrical system.

I installed at pioneer headunit back in August.

I'm going to test the blower motor resistor to see if that could be the problem, but still doesn't explain why the clock would go out.

If this happens a few more times I'm going to take it into the dealership.

It the clock stops working,pull it out and test for power and ground. This will immediately tell you where to start looking. The fan control and clock might share the same ground or even power. Generally the blower motor will have it's own fuse but will use a relay and a lower amp circuit to control it just like the starter and headlight system.
