Radiator Fans Problem

[seb928s]

Ok I notice today that the car is running hotter then it normally does. I replaced the water pump a few months ago because it blew up and leaked all over the place. So today I notice that when the car is on the temp if I'm at the light goes to 180 at the end of the 0. So I got out to take a look and the passengers side fan is running only I think on the normal speed. The driver side not running at all even when I turn the AC on the driver side one sometimes it turns on full speed but goes off after a few seconds 30 or so. At that time I think the the passenger side fan runs at the higher speed too. Then the rear fan in the decklid does not turn on at all. I checked the fuses for the front ones and they are good. My question is what could this be? Also how does the fan relay operate? I'm thinking maybe it's the relay going bad but I'm not sure.

Probably the ballast resistor.

It has been covered here before.

What I see that if I have the AC on sometimes the fans will run on high if I just turn the car on after it's been sitting while the engine is still hot. Still driver side only works on high but doesn't always work. Also I notice that the after I shut the car down the fans won't kick on to cool it like they used to do not so long ago. Could this be a relay issuse?

Here is the DIY on the ballast resistor on a boxster. Loren

has one but this one has more pictures.

You guys think it's the resistor since only one side is working and the other side not working?

[Loren]

The resistor is just for low speed operation so if high speed works and low speed does not the it pretty much has to be the resistor.
