Hi all!
The rad fan on my MGF 1997 (with AC) does regretfully not run. Have read a lot of threads, and with aid from these the following has been checked and done:
Fan(s) runs when 12V applied directly.
Brown plug on temp sensor removed (nothing happens while ignition on).
12V and Ground measured ok at the Relay module.
Fan relay inside the Relay module reacts when given 12V directly (and of course the fan runs then).
No signal measured on the "UY" from ECM to the Relay module, when ignition on.
Has anyone experienced that the ECM is "dead" on this issue only? Or are we missing something here?
Appreciate any input, this is more or less the last headache on the car before the MOT - for the time being
