So this is my analysis of the situation....

Cooling system is functioning normally, the only problem seems to be in one of the fans, and the ac charge...

Since my AC charge is a bit low...I think the pressure is insufficient to kick on the fans on low speed as needed. so i will have to address this problem. AC comes on without the fans, therefore heat goes up and engine tends to be toasty......eventually they do come on on low speed, but they take some time to do so..

I will need to clean and trace the connections on the second fan to see what is going on with it....it occasionally seems to hesitate to come on, so something is not right....even when it comes on, it seems slower than the other one...although i think it is a connection issue since it works fine most of the time....and when it is not working, pushing it, tapping it, spinning it does not make it work so maybe it is not getting power...?

what do you guys think?

thanks for the responses, and thanks Macdrone for replying on the other forum also
