We have bought a new computer for our 1991, but now know it was already replaced at least once. We are trying to figure out what is causing the computer to go bad. We have not heat, but the blower works. The floor of the passenger side is wet. Thinking thermostat. Any ideas where it is? Thanks

 

Heater core or a hose has burst

No heat is more than likely the blend door actuator has gone bad. A common issue with these cars
