Hey guys! I have a 99' Eldorado, and i have recently encountered a security system issue, which potentially doesn't allow me to operate anything electrical. Radio, gas cap, trunk, etc. The dashboard blinks as well. It first started when i picked up my car from the body shop due to a minor fender bender. He the changed the battery, and that's when it all occurred. It's currently at the dealership as we speak. They're searching for the issue. But! anything helps at this point! Thank you!!!

 

My 99 Eldo is literally having the same issue!!! It's at the dealership now, and they're already hitting me with a $500 charge just for looking at it. Taking my car right back, cause they are highway robbery. If you happed to find the solution, pleaseeeee help me also!?!?

 

I had exactly the same problem with my 97 Seville, no one knew what to do about it, I solved it by selling the car,
buyer was advised of problem, apparently 97-98-99 were the worst years for this.

 

What bypass do I need for my eldorado 1997 I have this same anti theft car no restart problem for two months now. What is the most guaranteed to work? besides going to dealership. Please and thank you and is there a world diagram for the bypass or is it just a plug in play?
