MSM Cooling Fan Control Relays - All 3
 

There are three relays mounted on a "brass" pedestal on the driver's side of the engine bay, near the front - also near the diagnostic port).


These are all identical relays marked as "H270". The stock units are manufactured by Imasen. They are available on Rock Auto, Summit, and Ebay. Actually, right now, Ebay suppliers seem to be the only ones who have them in stock.


These relays control both fans - cooling and A/C. There is not much documentation on how they work, or how to trouble shoot them, other than how to wire both fans to work identically.


As far as I know, this is the only relay identifier online with a part number!
