My first thought was "substitute the relay" too, but I soon found out from the guys with experience that such isn't the case. "Module" which is of course "serviced as an assembly" instead.
Also, JD, I like that work around in the above post. I was not aware that they had made a nice wire in kit for this. It goes to show that this is a known issue with ford on these fan assemblies which also house the module/relay which as you so aptly wrote (serviced as an assembly).
I like that work around better than cutting a rad hose and fitting a thermo switch in. This kit has one that excites the relay and has a wired in fuse too. Way less hassle than doing that as I used to do myself.
I am just wondering where that thermo/ect sensor goes and will it bypass the PCM internal reading of the actual ford ect sensor. I am going on the assumption that the PCM will code if the actual ect sensor is not being seen. Maybe it would be nice to splice in the OEM two wire harness to the new thermal switch so both the new relay substitute patch and the PCM can read the actual engine temps. I hope what I just wrote made sense.
