    I fired up the Blazer today to go to work, get a mile down the road get above 35 and speedo goes nuts, turn down the stereo and you can hear it spinning, oh well it came loose I thought, then look at my thermostat and it is buried in the not good direction, Im like oh crap Im screwed, stopped all looks good engine sounds normal, get halfway to work and everything goes back to normal wtf? Anyone seen this before, gonna have to pull ye ol dash this weekend to see whats up. Its an 88 so it has a mechanical speedo

    If it aint a Chevy don't raise it up!

    My '88 did the same thing right after I bought it. It has never done it again. If yours isn't doing it any more, don't mess with it.

    My speedo just started squeaking, annoying as hell when I'm on the highway. I don't know what's wrong, I'll deal with it when (and if I ever) I change my dashlights. I just turn my stereo up louder and it "goes away" [​IMG]. Never had my temp gauge go nuts though.

    My speedometer doesn't work when it is cold. I think it just needs to be lubed. They make a speedometer oil that you can buy from a dealer. I think you have to put it in from behind the gauge, and I'm so busy fixing other stuff I don't want to pull the thing apart right now.

    I always take the cable off at the transfercase, and "pack" the cable with grease. I use a special speedo lube grease. It will take a few miles for the grease to "work" its way up the cable. Works every time for me!
