Be better to put this in the technical section than in the for sale section.

When those fault codes are set, the ECM may turn on the cooling fans and run them all the time.

You have to diagnose those codes then repair as necessary.

Do you have the Factory Service Manual for a 92?

problem solved. 92 lt1 cooling fans coming on early. previous owner installed rheostat in radiator to make fans come on early and stay on, for road racing I am told.disabled rio switch and fans come on and off close to factory settings. Yes I have factory service manual, it is a must with this car. and yes I know I posted in the wrong spot , I'm new to computer but am learning. thanks for your comments. happy pappy 92.
