I have an 03 sable 3.0L. I''ve replaced the mega fuse and its was working fine for 1 month and 1/2 but now yesterday the abs light,brake light,air bag light came on again and the RPM''s shut off. And the auto dimming mirror went out and yes the alternater has been replaced. I turned off the car at walmart was in there for five mins came back out started right up and ran perfect. Its like its has good days and bad days. Help me please thank you![img]smileys/smiley1.gif[/img]

 

All these problems existed and were fixed by replacing a (one) maxi-fuse? And now they come and go? I need to get specific before I speculate on the problem. Let me know.
