Default problem with the radiator fan when I turn the A / C or defrost

I have Pt Cruiser 2002 and I have a problem with the radiator fan when I turn on A/C or defrost.
When I turn on A/C or Defrost, radiator fan is switched on immediately and includes alternating low and high speed in four of five seconds continuously!

what's the problem?

Normal for the fan to kick on when AC or defrost is used, as for the high/lo fluctuating speed not sure. Some one will chime in about it.

You already asked me the same question in a private message. Why didn't you wait for an answer which I gave you there?

I was in the service and found that gas is fine, but that does not have high pressure, and therefore a/c compressor is switched off and on for a few seconds when low pressure rise. compressor is switched on and off alternately, Say that something might be clogged? What can it be?
how to solve the problem?

If it's clogged, you might have to discharge the whole system, and recharge it. Might be a job for a professional.

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.
