Since the alternator was replaced, many strange things have happened. The cluster lights went out but the fuse was good. had to replace all the bulbs in it but still no good. The radio and clock fuse also blew but that was replaced and they are fine. The parking lamp fuses blew but after some time and a few fuses they seem to be working again. Now the signals are not working and we are hoping a flasher relay is all that is needed. Is it possible that the ECM was compromised during the alternator replacement? What can be done?
