On hot days, when I start the car, the ABS light comes on and the AC does not work. If I turn off the car and restart it, it goes away and the AC works fine. Can someone help me find the culprit of this? I have some problems with my sound system as well. I'm thinking it may be related. The previous owner decided to upgrade components and add an amp, but he kept the OEM cd player. Sometimes, it takes several minutes for music to start playing. The headunit shuts off. The mute button comes on and I have to turn it off as well.

 

sounds like a short or a bad ground somewhere.have a auto tech ck it out.
