I have a 98 Amigo 2.2l. The electric fan will not come on til the engine coolant temp gauge is almost all the way hot. All sensors have been replaced. I took it for diagnostic and all connections, relays and fuses check out good. The diagnostic tool could not recognize the ECM or PCM. I also noted that when I turn the key on the check engine light or oil light does not light up. Mechanic said replace ECM. I replaced with one out of 99 2.2l still gets hot lights still does not come on and gas gauge stuck to over full. My question is are the ECM/PCM enterchangeable (from 98-99). Is there a reset procedure I need to follow? Or any other advice other than straight wire the fan and hope for the best. Thanks so much!
