i recently changed my factory radio and now my car will not start. i looked at the fuses and the one that was blown was the ign fuse..so i changed it but it keeps blowing ...also the lights on the dash dont work either when on the "on" position (check eng. ,srs, etc.)and the windows/radio wont work either when on the on position.....anyone know what the problem could be?

 

Obviously this is your installation. Double check all what you did, you'll find the reason. Most probably you just grounded something that should not be grounded.

 

^^^ i deffinetly agree w/ misha, you need to take that radio completly out and start over. the ign fuse blew because you probably have the switch power to the radio crossed with a wrong wire. and depending on what year car you have, most of the circutry is all linked together "somehow" and all needs to be closed in order for the window, dashlights, stereo to work. be very carefull and make sure the car is off. good luck

 

check ur 12V and ground wires and make sure there not touching....this might cause the fuse to keep blowing
