I've had a similar problem with my 90 suburban. When I asked the people at my local auto store, they said look and see if any of the sockets looked scorched/burned. I don't remember what they said about that, but I'm sure if you told someone who knows cars you had scorched sockets they could probably tell you what your problem might be.

If you replaced every single bulb, my next suggestion would be check for a bad ground, or even a cut wire (that was my problem, I had a cut wire right in front of the rear bumper. Don't know how it happened, but that was my problem.)

95% chance that it is a ground problem
