Temp gauge doesnt work, never has since i bought the car

its not the gauge fuse, all other gauges are fine

its not the sending unit, tried new one w/ no luck

its not the gauge itself, also tried replacing that

What is it? Whoever can help me with this will win my forever ultimate props award!

 

I assume you mean the needles just sits at the bottom of the guage and doesn't move ever? Not even when you turn on the ignition? IN that case, check for grounding issues. It can't read if the sender and the guage aren't grounded properly.
