Ran my A/C for a few hours. Shut off the car for about an hour, turned the A/C back on and the A/C button flashed about 4 or 5 times and then shut off. My son told me to check and replace the fuse and relay. Which I did but that didn't help. Outside temperatures yesterday were around 96 when it stopped working.

Yep, this means there is an error in the system, it could be the system is low on refrigerant. We need to run the codes to see which ones are stored. This video will help:
