it's highly unlikely that it's burned out

probably it's not there...
how exactly did you try to reach behind the dash? I don't get it...
Just drop the wheel column and start unscrewing covers. You ll have to remove the trim around the gauges and pull it out. It will flex but don't break it; make sure you have turned the wheel such that you have the most possible space. For my 96 I also had to be careful taking off cruise control socket etc.
There should be a guide in nico. check tech pages -but it's fairly simple.
