    99 cadillac sts trunk keeps popping open when driving only

    It's pops open when I'm driving on the freeway, street, slow, fast, bumpy or smooth! the trunk opener button that's in the car under the dash next to the gas cap release button does not work. So I'm kinda thinking it's an electrical problem but on the other hand the latch is real dirty(looks like oil)??? Any help would be appreciated

    Shop manual should tell you how to test trunk latch. I believe that the procedure would be the same for most caddies make in the late 90s. (94 to 99)

    (I had a manual, but someone borrowed it many many moons ago. Not sure where it went.)

    My gut feeling is that the problem lies in the front switch under the dash. I drove a Caddy about 5 years ago that did the same thing. You can likely locate that switch on craigslist or ebay for $25 or less. (Just a guess on price--maybe $10.)

    You could also ask local gm service mgr to dig up some TSBs on that switch. Probably cost you a few tacos for that research.
