Hi... really lost here...
My wife and I have taken her Mustang into two auto service shops within a week trying to get her AC working. The first time the car died while idling and they found the alternator was bad. I had just put in a new PepBoys ProStart model last year. They charged the battery and we got it home. I took the old one out and installed a new onsite-tested ProStart rebuilt part into the vehicle. Afterwards the battery console light would not go off so we took the Bosch battery in and they said that was bad too. At $42 prorated (not bad), I installed the new battery and the light went off. Good right? 12.9vdc off/13.8vdc engine on...
Yesterday we took the vehicle to a friend-recommended auto shop. The SAME thing happened again! While checking the cooling system the alternator would not fully charge the battery and it eventually died. Upon getting it home I tested the battery terminals and it read 12.9vdc off/12.4vdc engine on.. another bad alternator one day after replacing it!
Though they can get one, I don't want another rebuild from the auto shop. They offer a "new one" but honestly I don't trust that it will be new unless I install it. What should be the next course of action? Do Mustangs require better parts than what I've settled for?
(BTW, the second shop determined that the AC compressor core was bad. It just gets better all the time
