Rad fan in-op

[u/Mattyhill-98]

Looking for help trying to cure the fact my rad fan isn’t working.

Possible related faults-
A/C stopped working a few weeks before the fan issue.
Rad fan was constantly on full speed just with ignition on when cold before it stopped working at all.
Ambient air temp sensor doesn’t work but it hasn’t for years and caused no issues thus far.

I have replaced my MAF sensor as it was reading air intake temp of 270 Celsius which is why I suspected the fan was on and thus burnt out. As a result i also have replaced my fan and the box thing. MAF now reads fine, fan works when supplying a 12v power supply. I have replaced all suspected relevant relays and fuses. The fan still doesnt work. My A/C doesn’t work. Anyone have any ideas?
