It recently got really hot and humid out and all of my electrical parts in my 06 Mustang GT work then they dont work, like my A/C, headlights, blinkers, power windows, radio, and also my parking break will think its on but its not, it will just beep until i stop.

It got worse as the days went on, my dash said "check charging system", "check brake system", and "check ODO meter error". I brought it in and they didnt find anything wrong with it, the car was a salvage title, it has rust and mud in parts of the car. Do you think that non ford parts were installed or rust is blocking a signal or something, it worked all winter in Minnesota completely fine too.

 

Might want to post this in the section for the new cars. It is all classic guys in here and I know I can't help you with that problem.

 

Check the main ground from the batt to the car. Then check all the small grounds. This sounds like a ground issue.

 

thanks for the advice, ill ask the mechanic about the ground issues. and sorry for threading in a classic mustang group

 

The earlier S917 cars have had problems with cowl leakage that screws up the Smart Junction Box that I suspect is common to all of those ailments. Of course, the fact that this car is a salvage with evidence of flooding is likely a separate cause of what I still suspect are SJB problems.

Try the 2005-up technical sections (4.6L Specific). There are guys there who are more familiar with late model electrical stuff than I (I'm more of a chassis guy).
