EF thermo fan problem
My EF XR8 seems to have a problem with airflow to the radiator, and I believe I have tracked the problem to the thermo fans. The fans are working, but I don't think they are switching to high speed.
I've checked the relays and can't fault them. If I force the relay output I get the fans into high speed. However, if I set the a/c to max and interior fan on boost, the thermos will not go into high speed (and these conditions should bring on high speed).
Anyone got any ideas on this?
