My 1992 Hertiage Packet Z-28 has two fans-one for the air conditioner the other for cooling the trans and coolant fluid. After replacing the cooolant senor, checking all the wires, and now seeing that the service engine light flashes "1 5"(coolant sensor open circuit or faulty ECM!!!) I'm worried I'll have to sink a lot money into a new ECM. Tell me I'm smoking crack and I don't need to worry because it is something small! Please, oh please help!

 

Where in Michigan do you live? If you are local, I could take a look at the car for you.

I live in Grand Rapids.
