I did a search and couldnt find which one was the high speed wire. I am doing a manual fan switch and just wanna run the high fan instead of having a switch to toggle between the low and high fan. Any help would be greatly appreciated. Thanks!

If i remember correctly blue was the high speed wire. But i'm not 100 % sure, I do know that shoebox would definatly know for certain. Just ground each one from the fuse block under neth the hood. Which ever one triggers the high fan is the winner.

 

Hi and low fan speeds didn't start til late 94 and also have 3 relays for fans..
Early 94 [not positive about 93?] have primary and secondary single speed fans... 2 relays only..

 

Yep, Blue it is.

 

If you want both fans to run, you must ground both blue and green. On a 1993 there is one relay for each fan and they run at high speed when they are turned on.

 

Thanks guys
