So I just purchased a 2007 V6 Mustang with relatively low miles for a good price. All runs good except that I noticed that after driving for 30 minutes or so the car starts having problems. The AC, radio, and interior lights and even high beams start flickering. I’ve tested both the alternator and battery and they all seem to be perfectly fine. Essentially the electrical components are struggling.
I’ve noticed the battery on the dashboard flickers all the way up to high then back to normal when the flickering occurs.
check charging system comes up.

 

With All The Rain We Have Been Having Lately You Need To Check These Issues First I Would Advise!

Has this car ever been exposed to interior water leakage thru the passenger side cowl panel? if it has, it's very possible that water could have got into the smart junction box, located in the kick panel on the side foot panel below the glove box... This is just a guess on my part, but you may want to consider having your fuses and electrical components checked in your smart junction box for any possible shorts or damages to your modules... In the meantime, sorry that I couldn't be more helpful.
