The ac will randomly stop working and start back up, the dash lights go on and off, and the radio works about half the time, with it switching between aux and radio, all by it self.

 

clean your engine grounds and check altenator. a bad altenator can yield low power or wacky electrical issues(fluctuating voltage)

 

electrical gremlins like these can be caused by faulty alternator diodes

i've had a lot of luck with Pure Energy alternators and starters

for remans you can purchase a return label and they will deduct it from your core when you send it back and then issue the credit

also you get roadside assistance
