I changed the bulbs in my instrument cluster and my temp gauge quit working a fuse was blown I replaced it and it works again but it's maxing out like in the red when I start my car even though my engine is not overheating it worked fine before would read in blue when start and go right below halfway when driving I have plenty of fluid and not leaking anywhere also my thermostat is fully functional what did I do wrong when reinstalling my instrument cluster and dash somebody please help.

 

It's possible that you pinched a wire. Pull it back apart and check

Not seeing any pinched wires anywhere I was careful when doing this as to not mess it up however my battery was connected at time of uninstall/reinstall it did blow a fuse is it possible a backwards fuse would do this?

 

Did you check the pins when you took it back apart to make sure that none were bent and touching?

I tried reversing fuse and did nothing at all I also noticed when I removed the fuse it shot straight up to hot so lost here I do not understand how it could work with no fuse

 

Installing the fuse, is installing the fuse. You can't install them backwards

The gauge has fine copper strands. If you break it the gauge will always max out. You might have to find a used cluster and replace the gauge. The gauge is usually held on by 3 screws, and one is shorter than the other 2 and if you put the screws on wrong, the copper strand will break.

 

I had 3 long screws no short screw thanks for help about strands I will looki had seen them before and looked alright but will check again

 

I did not see any pins is there a picture thy could show what you are talking about

 

It's been a while since i have taken a cd gauge cluster out. I could be thinking of my truck, but the pins on the cluster where the harness plugs in.

Okay I know what your talking about now where it plugs in those are all fine as well still need to look at coils haven't had a chance yet

 

Another thing about it is it maxes out before I even turn the engine on just sticking my key in maxes out the temp gauge

 

Is it possible electricity could ruin sensor if so how would I check it also if coils were broken would it ever return to cool when not turned on

 

If it does that, then you have a short in the ground wire leading from the sending unit to the gauge. You will need to trace this circuit to find the short. Start by pulling the wire off the sending unit and work from there.

 

Thank you it randomly came back on wire must have been loos
