    The dash lights seem to be getting dimmer and dimmer. I can hardly see any qauges at night. Do I need to replace the entire instrument cluster, or are there individual bulbs in there that I can get to? Oh yeah, it's a '78 K5.

    your head light switch should turn to dimm or brighten your dash lights. That switch could be it!

    Sometimes corrosion gets to the connections to the bulbs as well, although it is a bit of a job, you have to remove the dash bezel and the plastic clear cover underneath, remove a bulb at a time and emery the wires on each side of the bulbs and reinsert....

    Mine was doing the same thing. I put new bulbs and that brightened it up but two of the sockets don't work[​IMG], I guess I can just replace those[​IMG].

    In addition to Eagle's post, you "can" reach behind up through all the wires and mess and twist the little holders out. They turn about a quarter turn and pop out. The bulbs just push in-pull out. A lot of times a few burn out and a few get dusty, and the wires corrode etc. You have to be a contortionist, but you should be able to reach most of 'em from behind. It may be easier (if your back is like mine) to do what Eagle suggested and pull the bezel....at least you can do that while sittin' down.....with a beer close by!! You can get new bulbs at any parts store.

    Yeh yeh, I know 'bout the switch. (oh - you can dim them by turning that??) :-)
    Thanks for the suggestions guys. I kinda like the "sittin' down with a beer close by" method. I might as well take the whole thing apart since I really need to mess with the speedometer as well. As soon as I accelerate, the needle starts jumpin' all over the place. It'll calm down once I get to speed - mostly on the highway. In-town driving really sucks cause I can't tell from the speedometer how fast I'm going. It's a guessing game from there! I'll have to check the cable connection, etc. etc.

    My speedo does the same thing in the winter when it's real cold. If you you figure it out, post your solution. Thanks

    It is called...grease the speedo cable, white lithium grease seems to work best as I recall. Pull the cable off the speedo and pull it out, drench it in the grease, then push it back in all the long adding grease, if it hangs up, twist it a bit. This makes for a fun job especially if the girlfriend and or wife helps, you get the cable fixed and both end up greased.....hehehehehehehe

    Delta - judging from what was said above, it sounds like bulbs. I'm gonna mess with it this weekend and I'll post my results.

    I had the same problem with the lights. I just replaced all mine. If I remember correctly, the bulbs are supposed to be 164s, but 194s are the same thing, or something like that. I ended up using the 194s cause we had a bunch of them in the shop already. It definately made a difference.

    As for the speedo cable....sometimes they get kinked or bent, and that will also make the needle jump. Someone makes a tool so you can shoot the grease right into the cable...like a zerk fitting.
