ANother hot day today
Wife rings to say get this A?C fixed, cannot go another year without it operating properly

I have reverted to Rhiengold to test.
Tonight - the AUx fan runs as soon as I started the car. 27C displayed on instrument cluster and at a setting of MAX air cooling, fan runs and starts blowing cool air

I got revealed Fan Motor issue with Rhiengold - but now after reset - no errors and running well

So - is it a fan issue, relay or something else buggy???

WHat to try next?
