So I bought a JVC stereo at Best Buy for about 50 dollars to replace the stereo that comes with my Jeep ( 1999 Cheroke Sport ). I took the old one out, while my door was open, so the lights on the inside were still on, I connect the new stereo to the Jeep ( with the battery of the car still plugged in, stupid right? ) and then suddently the inside lights of the car went off.. I tried turning my car on and the new radio did NOT work and suddenly i realize my dashboard lights are working but the guages themself are not working.. I have no clue what I did or what I need to check. I have checked all the fuses relating to "Radio" and "Courtesy Lights" but nothing seems to work.. Even with new fuses.. Can anyone help me out?! Thanks! Jeff

 

this might sound weird but try disconecting the earth of your battery leave it off for 1o mins the reconnect it,then try starting the jeep its worked on other cars before worth a try

Check fuses #15 & 16, they're for the radio.
