You probably need to replace the fan.This is a pretty common problem on the PT.

If you know the fan isn't working, why not believe that's your problem instead of thinking it's something else making the fan not work? It's the most common problem that the PT has. There's two speeds and usually one or the other is burnt out.

Darn, beaten my seconds.

A few people I asked to get a couple different opinions, I was told that there could be a sensor or relay in between the temp sensor and the cooling fan...is that not a possibility?

Yep, there are 2 relays (high and low) for the 2 speeds of the fan. They are located in the PDC (Power Distribution Center) in the engine compartment. You can swap the high speed relay with the horn relay to see if it's working but the low speed has to be tested out with a meter. They very rarely go bad.

Easier to run a hot and ground wire to the electrical connection of the fan and see if both speeds are working.

Yea, finally found it. Was a little confused because didnt think the lid to the relay box WAS a lid. After inspecting it a while, I finally saw the clips on the side. Gonna test it tomorrow and get new relay if bad. Thanks.

disconnect the fan 3 pin connector middle is the ground and shorten 1 or 3 to positive while 2nd or middle hooked to the negative 1st and 3rd pin are the fan speeds check them both like 1 to positive 2 to negative then 3 to positive 2 to negative if one of he pair fails to start the rad fan replace it as it is the most common problems on earlier pt's
