Yet another thread on aux fans. I searched previous posts, but didn't see my problem, but then again there are 351 results for "aux fan".

With the engine at 90C and the A/C blowing cold, the aux fan never kicks on. I checked the connector underneath and found 0.0 V. Other threads talk about checking a relay and switch for this - where would these be on a 123? And what do I check next?

thanks,
