94 Chevy Instruments

[94Cheyenne3500]

got one for you all, maybe you can help i hope. i recently purchased a 94 3500 w/ a 5.7 2wd. my issue is my instrument cluster is acting more like i have 5 tachometers instead of the respective guages that are there. i have replaced the head unit and most of the sensors, however doing so has actually made the problem worse. there is nothing i can find wrong with the wiring harness or connections. it is most pronounced once the engine has reached normal opperating temperature. if anyone could be of any assistance i would greatly appreciate it.

I would suggest you try a more tech oriented forum than this one. Sometimes some people will have a good nugget of advice for repairs, but mostly we just bitch and moan about the auto industry. There are several for the GM Trucks. The only one I can name is www.GMFullSize.com.

I know there has been problems with the gauge clusters in the GM trucks, but I don't know if the known problems go as far back as '94 or if they extend to the 3500 series, but they're likely the same cluster as the 1500s I would think.

Best of luck.
