My 1999 Impreza seems to have cooling fans running constantly even in freezing winter weather. Changed temperature switch on intake manifold - no change although the old switch looked like it was in need of changing.
Temperature gauge always in the middle since before this fan issue and now with the fans (both) running almost constantly. Cooling level ok.
There seemed to have been a major issue with this on two other Subaru models beween 2004 to 2007 that involved a relay that eventually damaged the ECU - recalls, warranty repairs, etc. No mentioning of Imprezas having this issue.
Any suggestions what I can check?
Also 2nd time in 3 months check engine light that showed no error code and went away after reset at the dealer. It is not the gas cap as I watch that issue like a hawk.
Any ideas and/or sugegstions appreciated.
