I don't think my posts are making sense then. I will work with it a little more.

Have you, can you do the tests I outlined? I think I understand your posts, you just don't seem to be responding to the questions.

RACE ON!!!

Ok some test results. I took another connector and some cheap wire and attempted to ground the sensor/switch on the right side (passenger side). I got in and put the key to run. The temp gauge went to 299 so to verify I put it on volts and it read 11.3 and then the gauge auto reverted to the temp at 299 again.

Finally some progress.

I think if you install the temp sending unit that you installed in the left head, into the right head, where is belongs, you will have solved your gauge problem.

Next, reinstall the fan switch you removed from the left head and we'll see if we can get your fans working properly. Trace the green/white wire that connects to the fan switch (left head) and see if it runs back to the aux fan relay.

Only thing I verified was the fact that the sun was not simply causing the numbers to show...

I will see if I can just go get another fan switch cheap since I no longer have the one I took out.

Any technique for getting into the switch on the right side? It looks pretty tight.
