Im having a wierd problem with my radio,tach,oil pressure and volt gauges.when im driving all of a sudden my radio will just shut off,doesnt matter if its a cd or not.It also happens when i push my window buttons.The radio will just cut out then come back on.Ill also notice somtimes my tach will all of a sudden go to zero then bouch back up to were it should be,but the car will run perfect the entire time of all these occurances.Any idea on what this could be?

 

could be a bad battery ground so your battery isn't getting charged. check the battery, your grounds, and go from there. same thing was happening to my car and it was a bad battery ground.

should be around 13v-14v when the car is on, around 12.6v when the car is off. also make sure your alternator is still working.

suggestion would be, take your car to napa or shucks and have them do a battery/alternator test on the car. they should do it for free.

 

ive also noticed that when i push the window button down my autometer volt gauge and oil pressure gauge will dip then come back up
