There are 2 fuses under the hood in the fuse box to check. EF2 and EF3 if these are blown then the cooling fan won't come on. Please check these and let me know.

Please let me know if there is anything else I can do to help.

I was unaware of those two fuses. I'll check them and let you know what I find. It will be later today before I can get back to the house and to the car. What voltage should i see at the fan motor connector - 12V or something less?

You will see or should see a full 12 when the fan is on high speed, less when it is on a low speed as it works through a resistor. I am not sure how much lower it is, but I believe about half so about 6 volts.

Thank you for the rating and let me know how you make out!
