If the wire keeps coming off, all you can do is solder it. Those clusters were a stupid design anyway. They are **** because if they go, you can't even tell how much gas you have.
Make sure the wires are tight in the connector(s). If the wiring or connectors are loose, damaged or corroded, even slightly, it may cause problems. Remember, constant plugging and unplugging wears them out fast.
Also, when you replaced the cluster, was it new or used? If used, they may not be much good becaused they were probably used awhile anyway, but if each one has went the same way, then the problem is probably with your truck and it's wiring, connectors or something. If you can, check the wiring from the back of the cluster to where ever it runs. Chances are, the wiring is wrapped up and taped with other wires so the damage may be in there but trace it and check it as far as possible. A bad ground somewhere will cause your problems also.
Hope this helps.

I have a 1998 GMC senoma pick up. one of the injectors is stuck open and spitting gas...the truck shakes when it's idleing and sputters when i give it gas. my friend and i checked all of the wires...

Hello: The PCM provides a ground to fire the injector. !2v is always at the injector w/key on. Disconnect the connector and see if that stops the flow of gas, if it doesn't then you have a bad injector (replacement required) I it does then check that set of wires to see if the ground wire is grounded, if so that would let the injector continue to spray fuel. You can purchase a node light that the connector to the injector will connect and with the truck running see if the node light blinks if it does then the PCM is ok. (DO NOT USE A TEST LIGHT AS IT WILL PULL TO MUCH CURRENT AND COULD DAMAGE THE PCM)

I have a 1992 gmc c1500 and i dont have any power to the controls for my haet/air

came across this twice not saying without a doubt it's the cause but it's possible. Each time the power wire up to the control panel shorted out. Replaced wire and system worked good. Pull control panel out, look for burned wire, and replace. Been to long since I seen one to tell you exactly what wire it is.

My tail lights on a 1992 gmc jimmy just stopped working? anyone know why?

first check your fuses, then check the bulbs, then check the ground wires at the lights, then check the wires coming out of the switch with a light prob to see if switching the lights on and off affects the current in the wires coming out of the switch.

there is a vacuum line running to a vacuum switch on one of the hoses try taking the switch out and connecting the hoses together. Thats what turns off the hot water while the air con is on. If that works then its bad or the vacuum line going to it has a problem.
