Default PT 2002 LOW AND HIGH SPEED NOT WORKING

I will be grateful if any member could help me please. I have a 2002 pt 2.0l, 75k
The fan is not working, the Radiator sensor, thermostat, radiator cap and low and high speed relay. I can confirm that the fan motor is working
However I noticed that the when the radiator started boiling and making some pop noise, i switched on the air condition, the high speed was activated but this will not come on again: confused: please help
Please can any member help ?. How do i wire the radiator to come on as soon as the engines start?
Many thanks

The fan has two speeds and they fail all the time. I would replace the fan before you overheat and kill your engine.

Many thanks, Do you think the fan is gone, checked it and comes on when aircond is switched on.

You just said you couldn't get it to do that again!

At least one speed is gone. Replace it. Try ebay, rockauto.

Sometimes when our fans are going out, they work a little, then they don't. In other words, sometimes they just don't quit altogether. They're like kids that keep moving back into the basement ....

Our fans can even run too slowly--but still run.

We're in the same boat, check out my thread with my wife's 08'. I'm considering an aftermarket performance fan but i'm unsure if the oem relays will make it run the two speeds. You should be the guinea pig and try it out for us! Lol

Guys, I've seen postings time and again about the radiator fans and guesses as to diagnosing the problems, overheating engines, etc. In the OEM Service Manual there is an entire section dedicated to the engine cooling system and how to troubleshoot it. I was going to post this in my library thread but it's locked, so I'll post it individually until Crewzin unlocks it.

Now, the service manuals are different for '06 and up, however if I were you and I was troubleshooting overheating problems, I'd download both because they both have excellent info in them.

Here they are, you can download directly from my web library:
2000-2005 PT Engine Cooling System
& 2006 and up PT Engine Cooling System.
