My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

The only time it would blow those multiple fuses is if the alternator was changed with the battery connected.

Does the vehicle start and no other power issues? Is the alternator OEM? Also, a defective alternator can send out too high of voltage and disable all those systems and blow fuses for all those systems, including damaging them.

After replacing my alternator and battery my low beams air conditioner and I can’t use my power locks on my 2006 Ford F-150 4.6 V8

No other power issues besides the ones I listed and yes the alternator is OEM

Now with the AC not working, that is blower and all correct? Or does the AC clutch spin? This is to help determine if this is fuse and individual circuit blow outs of fuses or if there is a common ground that may have been affected.

Was the alternator changed with battery cables connected at all?
