1997 Buick park avenue - windows and door locks will not work

[Msgt45]

Hi,
I went out to the car and put the key in. The security system went nuts. I was able to get that to shut off however now nothing works on any doors. Windows, door locks, seat memory or mirrors. The door ajar is always on now also. I believe that there may be a fuse that is blown however the book doesn't specify which fuse is for these items. Can someone help with that or am I on the wrong track here? Thanks for your help.

There is a 30 amp circuit breaker in the fuse blocks for these. Neither circuit has anything in common with each other. Also a 15 amp fuse for the door locks.

If fuses and relays are ok, then I would start looking at the master switches on the drivers doors or the wiring where it comes from the master switch, through the door post and to the fuse blocks. I have seen wires break and even seen where field mice have made nests and chewed the wiring harness under the fender well and under the hood where these come through the body panels.
