Default 08 Pt Cruiser cooling fans not working.

I own a 2008 PT Cruiser and having some issues. I can drive the car fine and it doesn't overheat when I'm constantly moving, when i idle thats when it starts to heat up. I notice that when i take the battery cables off the fans turn on for a few minutes then stop... but after that they won't turn on when idling. Is there a sensor causing this issue? Anyone ran into this problem???

Please help! and thank you in advance for posting any comments

Default Re: 08 Pt Cruiser cooling fans not working.

From what I've been learning the fan is a very common problem. The fan will only come on under certain conditions.

Engine running but not warmed up - AC turned off - the fan is off

Engine running but not warmed up - AC turned on - Low/or High speed fan should come on

Engine running and warmed up, low speed or at stop light - the fan will come on when the engine reaches a specific temp (hot), run until it cools to a lower temp then turn off. this will cycle on and off while there is no continuous higher speed air going across the radiator.

There is a huge amount of threads in this forum that talk about the fan, it causes all kinds of other issues with engine shaking, AC hot/cool. If you suspect the fan, search further on the forum and you will find how to test, replace (not to hard). I am doing the same thing on my 07 PT.
