Test all your fuses with a test light when the problem is present. You probably have a bad contact in one of them.

Thanks Wrenchtech, can I buy a test light and if so how much do they cost? The wierd thing is it doesnt happen all the time but with this heat we have been having in Missouri its too hot to drive with no ac

You can buy a decent one for #20 or so. Try to get one that uses LEDs instead of incandescent bulbs because they won't harm the computer.

Ok another question do I test the fuses in fuse box under hood or on side of dash, and do I do it while it is running? And how do I do it? Sorry I am not not very car smart. I am just trying to fix the problem without spending hundreds of $ if I can fix it my self. Thank you

You test ALL of the fuses with the key on. You leave them in the socket. There is a metal contact on the top at each end. If you only have power at one side and not the other, the fuse is burned out.
