2000 buick regal LS

[Texasboi79]

Can't find the location for rear and dash Integration Module on my 2000 buick reagal. The reason why I'm looking for it is because , when I crank my car and turn the a/c on high put my car in reverse all of my gauges go to zero , check engine lights come on abs light comes on trac light . And if I'm driving down the street , and I have the radio on and a/c all of the gages drop to zero , the radio goes off and the a/c goes off. The car stalls a little bit then every thing comes back on . I have checked battery terminals alternator wire , tested battery and alternator. It also does this when I have the a/c off if I crank it put it in reverse and roll back a few inches the gauges drop to zero and all of the dash lights come on .

Where did you find the name "Integration Module "?
Google comes up with nothing by that name.
Do you mean Body Control Module, BCM?
Have you checked the battery ground, the fuse box connections, and all other engine grounds?
Have you considered a bad ignition switch?
