Hi There was alternator issue in my Toyota Camry XLE 2006 V6 i took it to mechanic he replaced the alternator since then I am having few issue with my car and getting code B1442,B1421,B1423 and B1424 and also giving the race it is noisy and not getting accelerated as earlier it was and he is saying to go to dealer now.
Also dashboard option for FAN/AC/HEATER taking some time to get on...
Any suggestion will be appreciated also how we can check if alternator is working fine.
