82 Z28 - temp gauge pinned????

gurus....today I noticed the temp gauge in my 1982 Camaro Z28 was pinned right off the end. It usually flickers up and then to the bottom with key on/off, but it does NOTHING but stay pinned now. Its got the full gauge
package (big speedo, big tach, small volts, temp, oil pressure, and fuel). Running a 160 deg thermostat, and the gauge ALWAYS read correctly.
could it just be that the sensor in the side of the block is faxored? is there a surefire way to test if its the sensor or not? if the gauge is faxored, I intend to get a sensor designed for a dummy light and trip a small LED somewhere....but I hope not!!! its a very warmed up 355 if it matters (original 4 bolt block from a 1977 4x4 camper special)

Sounds like a bad sensor. A couple of bucks at any parts store. Change it and be done with it. Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 27k orig.

Actually you're all wrong :-) I took the gauge cluster apart this evening (very easy to do on this model). the key happened to be on, and I just pushed the gauge cluster (to release the metal backing) and the temp gauge came back!! I put the dash back together and took a spin, and noticed as I left the gauge went wonky again....simply pushing on the bottom of the custer (above where the warning lites are) and it came back. has been working ever since.
next question: wtf???? after 22 years the connection at the back is loose? from what I could tell (I didn't have enough nerve to pull it apart past the gauge lense) the three small gauges kind of "press in" with long studs on the back that engage in brass tangs. is this close? could it be something flakey in there? perhaps the gauge itself is going wonky? any thoughts?
I haven't driven the old girl in about 2 years, and decided to pull er out this summer to clean it up and try and sell it. I'm happy to report that after all that sitting the only glitch is a wonky temp gauge :-) oh: http://members.shaw.ca/installz/for%20sale/1982_Camaro_Z28_1_files/frame.htm in case anyone cares.

22 years is a pretty good run for those clusters to work :) Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 27k orig. '79 "Y89" 400/4 speed 10th Ann.
