Question
QUESTION: HI MY NAME IS ANTHONY I HAVE A 92 caddy deville 4 door that ive had for a week now.My problem is i was drivin and i heard a crackling like distortion and radio turned off along with my digital gas gauge and ac digital display?wat is your opinion on this?i have check ALL fuses under the hood,under my steering wheel also the internal fuses under the glove box the number 11 20a fuse was blown put new one in and same problem .thank you
ANSWER: Hello Anthony,
The very first thing I would try if I were you to possibly isolate the problem would be remove the stereo and disconnect it completely. Replace you blown fuse and see if your digital fuel display continues to work without blowing the fuse. If so, you have a bad stereo or wiring going to it.
You did not state if this was a factory stereo or an after market unit.
I have seen some very bad stereo installations and that may be what you are dealing with.

QUESTION: It is a aftermarket stereo I already disconnected the radio and put a new fuse and nothing has changed has been like this for sa week now.I wish this could be the issue because it would be much easy to just correct the wiring for the stereo.any other ideas thank u
Hello,
If not the stereo, it can be very costly to guess what is blowing the fuse. Something in the circuit has a direct and immediate short. Whatever you do, don't try using a higher amperage fuse.
I do not know your capabilities. If you can get yourself an electrical manual for the car possibly at Ebay, you could see what is on the circuit and eliminating items until you find the problem.
I would recommend taking the car to a service center where you trust them and they can attempt to diagnose the problem for you. Whatever you do, there are two places not to go to. This can be a complicated problem, but it could be easy too. Do not go to the dealer or some alley mechanic that will claim he can fix anything.
Good Luck!

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
