Your blower fan had jack shitt to do with it.

Duracrap is crap....You'll have better luck with a Boneyard unit than you ever will with a Duralast.....also most junk yard alts are only like 30-50 bucks.

Yes, NAPA alternators are very, very nice.

Also, you get 7% off if you show a AAA card at NAPA. And some Discover cards have 4 or 5% rebate off right now for auto stores(and some gas stations), if you sign up. You can actually get both credits on the single purchase!

Naturally, pay close attention to the other things the admin/gearheads suggested.

Go get your money back and get a rebuild from NAPA or another suggested source. Replacing your battery cables and battery at the same time would be a VERY good idea.

Duralast ANYthing is absolute garbage.
best advice posted here. please follow wren'* suggestion, (or at least the cable replacement.)

You might want to read what I posted earlier today SJ. It tells what I had to do. While following Don or Bill'* suggestions of going somewhere else for an alternator would have been good, unfortunately it wasn’t feasible in this case. I'm also aware of who to trust around here. I've been here a while.

All I can say is those alternators are junk... But you do have a lifetime warranty.. So if it fails again... You'll get another one.. As long as you can get them and keep the car functional then you are good to go..

Brad got a 140 Amp unit thats functioning fine... I put another on the SSE and it to functions great.. Both JY units..

Andrew I thin whats happening most of the time is that the Diodes and Regulator are failing... My great uncle used to rebuild GM alternators all of the time.. And more than most of the time it was the Brushes, Diodes and regulator...

Andrew if you have more issues you will know where to look when the $$ are right..lol

Hows this unit functioning? Every now and again you may get lucky and find a good one

This one is doing ok right now. If it fails again, I'm getting my money back. I was in a situation where I HAD to get the car running. Going to autozone and swapping was the best way to get back on the road quickly. Hopefully this one will last me the couple months I have left until my truck.

well at least they gave you the new one rather than the reman. ive never used duralast. i prefer murrays over autozone, but id think it should last longer than the other. well hopefully anyway.
