i would try replacing both bulbs. I had to replace my bulbs often because of the DRL lights being a low voltage running through the bulbs. I think I would replace the bulbs and then disable the DRLs and see if that is a fix, to disable the DRLs all you need to do is pull the DRL fuse. Although with the replacement light, I would check the connections are still good.

The hold light is light a check engine light for the transmission. This could be a signal issue from on of the engine sensors, or something else entirely. A scan tool might read it, but most likely you will need a dealer to scan it.

The air conditioning and temp gauge can be anything, sensor, or a charge of freon. Those are most likely isolated problems. I do not know if the temp will cut the AC for overheating, some cars do that, so if the sensor has no signal, it could cause the ac to cut out and the hold light (should the Transmission wants to know engine temp?)

If the clock resets to 1:00, it could be the memory fuse, it is separate from the clock working.
