99 Mustang V6 problems.
1st issue, windshield wipes will not turn on at all. 2nd issue Mach sound system-the front door speakers and the rear deck speakers do not work, the only thing that works are the tweeters no bass. Im assuming its the amplifiers under the rear deck. How easy are those to change out? Where can i get some? Im looking into upgrading the receiver as well. I know when i first bought the car in 2001 i wanted to change the receiver and was told it would cost alot of $ due to all the wiring from the Mach system. Any information would be much appreciated. Thank you.
