I have a 1997 mustang lx. The other morning I turned the heat on and it completely died. There was a buzzing coming from the keyless entry that I have never used and never had the remote for. I disconnected it and checked and changed some fuses. MY instrument panel is not working at all. I have no speedometer, rmp, gas etc or interior lights. The car runs good since I checked fuses. It makes a beeping noise when I start it figured thats because the keyless box is disconnected. Need ideas on what to check to get things working again. Thanks
