    Okay, when I bought my Blazer, I noticed that the temp gauge NEVER moved and the heat barely worked. I thought it was the thermostat opening too early...now the heat works better but the temp gauge still doesn't budge...Whats the deal..Is the gauge shot or is the sending unit malfunctioning? Let me know...Thanks for any input...
    Peace,
    Chris

    I'm having the same problem with mine too. I'm gonna replace the sending unit first, and if that doesn't work, I'm gonna get an aftermarket guage so I can see what's going on until I get some guages like Solo's.

    could be either one, most likely it's the sender. find the temperature sender in the engine, be sure the wire is hooked up to the sender, if it is, remove it, turn on the ignition, and have someone watch the gauge while you touch the sender wire to ground, when you ground it the gauge needle should move, if it does the problem is with the sender, if it doesn't it is a problem with the gauge or the wiring.
