My car has been overheating quickly lately. The electric cooling fan dosent come on until the meter is near the "L" in normal and thats when the temperature goes down some but most of the time its too late and the temp nevers get back past midway. Once you shut it off, its a rapid ticking noise and the fan will quickly stop and start until it finally keeps spinning but why after shutoff, and while that is happening the check engine light flickers with the fan.

How fast does it get hot and how hot does it get? If you turn on the ac or defrost does the fan come on and stay on then? Get back to me with some info and we will go from there

When you turn on the a/c the fan wont come on. The car will usuall get to the A or L in normal before it turns on. Once it turns on the fan itself feels hot. Its not the fan motor it may be a bad switch or temperature, but it will start to click and spin then stop.

Sorry just making sure we are on the same page ok. So if I understand you correctly when you turn the ac on the fan doesn't come on? Once the ac it on it should over ride and turn the fan on. Let me know so I know what to look at in the wiring diagram to walk you through some testing ok. All you will need is digital multi meter.

Ok got it now. So if you would unplug the temp sensor for the computer (not the sender for the gauge) while it is running if all systems are working the fan should go on as this will make the computer go into limp mode. Let me know what happens and we will go from there.
