More fun with Fan issues... Different car... - ZR-1 Net Registry Forums

Been running into mutliple issues lately.. Now the fans in my 1991 do not come on even when signaling to turn them on with the Tech one, sometimes they turn on for a split second and off.... Now the odd part, if you go into service/Diagnosis mode it will turn the fans on as it sound.

Temp gauge seems to be working per the tech one.....

Cant win I am thinking this is another ECM issue

Thoughts?
