I searched this and am thinking it may have more to do with my problems then I thought. Since my PFC came back from XS and I relocated my battery at the same time as soon as I turn the key for the ignition(even in auxillary) the fans turn on at any temp. I have grounded the block and this helped with the break up a bit but could there must be something very wrong either with the XS programming or with the electrical system. Can some one give Me a few more ideas of what the hell is going on with this car!

 

Steve, I noticed that your fans would stay on all the time even before xs mapped your pfc.

 

Ya, I know. When I had the stock ecu in and before I did all this major single stuff, they did not run all the time. I wonder if it all has to do with the shitty harness? I removed so many things in the single conversion, it has to be something stupid or the harness. I am going mad and this is pissing Me off now.

 

If the wire on the themoswitch gets rubbed bear and is grounded the fans will run when the battery is connected it happened to mine
