    Hey guys!
    I've noticed that my oil pressure light never comes on when I turn the key to "on", but my alternator light does for the bulb check. Is it a difficult job to remove the instrument panel and access that bulb? I have about 7 screws on the front of the panel holding it on. I'd assume you just removes the screws and the panel comes out?
    Thanks!

    Even on older clusters, the bulb sockets are accessed off the back. Since you'll be back there, you might just want to do all of them, indicator and illumination at the same time.

    You`ve got to disconnect the Speedo cable as well. If you want brighter instrument lights, change to LED. Relatively inexpensive.

    In addition to those 7 screws, you'll have to take off the speedo cable to remove the cluster.

    Further to changing to LED`s. Removing the BLUE `diffusing`inserts {plastic things} allows more light to the gauges. I found some red Led`s on eBay.

    Don't lose the tubes over the turn signal lamps.

    You might be able to just reach under the dash to get to it.

    Good call about grounding the sensor wire to double check the unit.

    Thanks for the replies! I was able to wiggle my hand up behind the dash and get the bulb out and replace it. I also replaced the ALT bulb since I was back there. Everything lights up as it should. :cool:
