electrical issues 98 buick park ave

Basically you have to find to somebody who knows what they're doing, and not too lazy to actually do it. It means laying upside down under the dash for a while, and really looking hard at the wiring. That means taking apart wires connected with tape and wirenuts, and redoing all connections. I've had a version of that in a couple cars I bought. Locks locking/unlocking randomly. My son fixed both by doing what I said. Think both were bad aftermarket alarm wiring, but maybe one was bad aftermarket radio wiring. But he's done of lot of this type of work on cars. Always replacing radios, and adding remote starters to cars. He still had to go after one car twice before he got it right. It's always been poor aftermarket work on the wires screwing things up. Not saying that's your problem, but it's a solid guess from what you're said.

Thank you Vic, I havent found anybody that has found the issues but I'm not gonna stop

I would also add that, if there ever was an instance when buying the fact ory service manual was warranted -- this would be it. Because evidently yo u are planning on keeping the car -- so why not? And nowadays they're surp risingly cheap on eBay, and you can have them in a matter of a day or two. Be sure and get the set that includes the electrical schematics.
