My wife has a 97 Catera we bought new, she loves driving the car but it has had it's problems, luckily most were fixed under warranty. The latest problem is electrical. The car will not shift out of park unless you override it by pushing the yellow button under the gearshift boot and the same that went so did the button on the dash for the fuel door release and the trunk release, now to open these you must use the key fob. Has anybody else ran into this problem? I'm looking for some suggestions on what this could be.

There should be a fuse that controls your gas and trunk release. I would check there first. I tried to look back through my manual but could not find out which fuse it was.

Replace the multifunction module (relay) located way under the dash to the left of the steering column. This module will normally take care of trunk lid, gas lid and radio not turning on. It is GM Part #90494163. It's a gray plastic box with contacts on one end.

That module should take care of the trunk release / fuel door issues. I'm not quite sure about the gearshift issue but i can look at the schematics and see if I can find a clue to that one.
Does the 'Brake before shifting out of Park" light on the instrument panel go out when you push the brakes to shift? Is it ON when you start the car? Do the brake lights work? These are clues to me.

Is there a good picture of what this module looks like in its snug little spot under the dash? I spent the morning hanging upside down under the steering wheel looking for this thing and my very untrained eye didn't spot it. (Observer error, no doubt.) I have the dreaded no radio, no fuel door, no trunk trifecta going right now and the gas tank is running uncomfortably low. And the no radio thing is...well, frustrating to say the least. Thanks in advance.

Sorry...98 Catera. I found a schematic and picture in another post...(http://www.cadillacforums.com/forums/cadillac-catera-cimarron-forum/99941-where-multifunction-module-99-cat.html)...and I'll be damned if I can see in the picture what was showing in the schematic.
