temp guage is not working on my corrado 1995. it has 3 sensors, yellow 4 pin, blue 2 pin, black 2 pin.
from what i gather, correct me if im wrong its the blue white wire on the yellow 4 pin connector i need to be looking at?
thers no votage on the blue white wire, i assume if it had voltage and was grounded temp should show max? similar to the fuel level sender.
is there a dedicated fuse for this circuit? i looked at cluster whires but they are all white so makes it hard to isolate a wire problem.
