SOURCE: fuel gauge stuck on half full

I can tell you almost for certain your fuel level sending unit is bad, I have been able to fix them though. It requires removing the gas tank and then the fuel pump. You can if your inclined, bend the brushes on the small circuit board over more so they will make better contact on to it. Other wise its a new fuel pump assembly, check all plugs and wiring by unpluging and repluging them to insure no bad connect. It is possible it could be the guage itself, but in thirty years of fixing cars never had a bad guage

look for a short in the sending wiring, empty means the circuit is closed, open circuit full

SOURCE: have a 2001 gmc jimmy...drove home gas gauge read

chevy and gmc trucks have an on going problem with this,turn the key on,and get a rubber mallot or a hammer and hit the bottom of the fuel tank a couple of times,this will unstick something in the fuel pump/sending unit.

SOURCE: gmc jimmy 1999, fuel gauge reading empty, even

the sending unit inside the tank has a open circuit that will not complete the signal to the dash gage. The tank will have to be dropped to replace this. The fuel pump is also a part of the sending unit. The part is not very cheap neither

1997 gmc rear air conditioner is blowing hot


Could be a blockage in the lines to the rear unit.
Might be low on freon too. Or a blend door problem.
Can you check under the floor and see if one of the lines is cold ?

I fully charged the air. It reads full. But the compressor kicks on and off every 10 seconds. And the air is warm. I used Artic Freeze Ultra Synthetic R-134A It came with a gauge assembly.


Overcharging your a/c will cause it to blow hot .The on and of issue may be caused by the High pressure cycling switch . overcharging may be the culprit as well. you need to find out how much r134-a your system takes .
