Need some help troubleshooting the cooling fans on my 94 AUTO SC. I'll list out what I've done and well what I am working with car wise also.
Picked this car up last week super neglected...runs smooth and strong but wants to over heat.
Upon purchase fans only came on with AC on or ECT sensor disconnected. I've replaced both the IRCM and the ECT w/ known good units. The fans now come on, on there own however the temp guage is usually past the M of NORM when they do.
Car has an LX cluster w/ VOLT guage in center..so not sure the accuracy of the cluster. Have known good cluster from parts car to swap in.
I've read on several other posts that the culprit may be the EEC but if fans are coming on (even tho when really hot) I assume the EEC is working as it should.
Other Items I will address - Replace T-stat, Flush Coolant System, replace cluster w/ 94 SC cluster.
Anything else I may be missing here in determining whats wrong. Trying to save another SC from the ashes.
