electrical gremlins

Another question.

I was at a stop light and my speakers just cut out and wouldn't come back on until I restarted the car a couple hours later. It has been ok since.

Also, my A/C sometimes doesn't come on when I start the car. I have to restart the car several times before it will start blowing. I have had all the recalls and it was just at the dealer and had the A/C control panel replaced through my ext. warr. (believe it or not, to the tune of $800). The dealer said that was it for sure, but it still happens about once every week, just as before.

Any ideas on either problem? Thanks in advance.
