So if you go back to the "not a happy camper thread" my car blew the num 21 fuse in the pcu. well it happened again yesterday, and then again 5 minutes down the road. each time i replaced it with a 20 am mini fuse, but they keep blowing. any advice?? maybe a short?

What fuse box was it in, the under hood of on the instrument panel?

 

under the hood by the airfilter

 

I haven't looked at my car or my disks but what a blown fuse indicates is not enough resistance meaning the power is going to ground. (shorting) Do you know what that fuse powers? Is it labeled? Have you done any mods to the car that affect that system?
Look for water intrusion. Look for wires bared and touching each other or metal. The entire wire run has to be inspected for rubbing, chaffing or otherwise compromised insulation. Does it happen in the rain? Finally, if the wiring is thoroughly checked and found good, I would suspect the unit/s that that fuse powers as failed or failing.
Hope this helps.....

 

I have checked all of the wires and everything looks fine. The description for the 21 is FP/ASD. . . . any ideas?

 

They have finally fixed the problem!!!!!!!!!!

After replacing the wiring harness, the dealership found that the plastic cord protector around a wire was rubbing against the master cylinder when i was making right turns. They fixed it and I haven't had any related problems since then.

 

congrats, you needed some good news

 

I know, I was so bummed for a while, now she's running fine!!
