Neither my car nor the donor had headlight washer. Which explains why this light was not operative.
About the CAT temp sensor: The resistance I got here was not working as it produced erratic resistance everytime I checked. So I visited the electronics market and without much effort got hold of a variable resistance (0 to 100 ohms). It works perfect once set to produce 15 ohms resistance. Before I connect it to ECM, can you confirm whether all I need to do is to connect the wires (red & white) to two interfaces of the variable resistance? Is there any thing else I need to pay attention to?
I believe if the light goes out, it means success.
