Having problems with your 1989 Toyota Camry ?

AC and Cooling Fans Not Working

\015 I have a '89 Toyota Camry with 4 cyclinders, 2.0 engine, automatic transmission. I'm having a lot of issues figuring out how to stop an overheat problem.\012\012In the past, whenever I started the car's AC, the cooling and AC fans sometimes turned and sometimes didn't turn. I checked both CDS 30 Amp and Fan 30 Amp fuses. They both worked fine. I've tried replacing the Fan Relay No. 1, AC Fan Relay No. 2, and AC Fan Relay No. 3. After the relay replacements, there was no change at all - sometimes the cooling and AC fans turned and sometimes they wouldn't turn. I checked the fans themselves and they both worked fine.\012\012Now both fans will not turn at all, causing overheating problems. When I start the car, I can hear Fan No. 1 working. When I start the engine and then check voltages for the Fan 30 Amp and CDS 30 Amp section to the ground, there is no voltage reading. It should have been a 12V reading if everything was working properly. It's strange that there is no voltage at all. When I disconnected the Water Temperature Sensor, I heard the Radiator Fan No. 1 Relay go to the off position so that part of the circuit is still working correctly, but somehow no electricity is getting to the Fan 30 Amp and CSD 30 Amp section of the circuit.\012\012What could be the problem? Any ideas on what to troubleshoot?\012\012Finally, where is the cooling fan ECU located in this model Camry? I can't find it in any of the diagrams in the manual. Is TCCS ECU the same thing as the cooling fan ECU?\012\012Thanks in advance for your help.\015 Posted / edited by AnonymousUser on : 10-06-2019
