Hey guys, I am trying to troubleshoot what is wrong with my brothers 2004 z4 3.0.
The other day it started to get hot while driving home (in Vegas its like 105+ outside right now).
We replaced the thermostat and it still got hot while after awhile.
I think it might be the electric fan, since it won't turn on while trying to diagnose the issue at temp. When I click on the Ac it does 1 revolution and doesn't spin anymore.
Any ideas on how to confirm its the fan or how to troubleshoot further?

Overheating / How to troubleshoot?!
Well welcome to the forum.
I'm pretty sure the fan should be running continuously, albeit quite slowly, if the AC is on. My Z4 needed a new fan for that issue earlier this year.

UPDATE!
While playing with the car trying to figure it out, I noticed the AC compressor smoked a little while the ac was clicked on.
I feel like I remember someone saying that if the AC isnt working properly the rad fan won't eiter.
Any ideas on that?
