Hey.....had the same problem the other day....with my `98LS....it was the Fan 1 relay....hope this helps.

 

Actually, Blazerman....You are who I was thinking of when I posted that link! So thanks for posting your previous thread and this one!

 

hey thanks guys its a 97 ls and the motor is 3.1 and i hoping to god its the relay lol did you check it and it did not click or how did you tell?

 

I have a haynes manual and traced the wiring schematic. Usually if a system has relays in it I go for those first as they take a hit after years of use. I went for thr Fan1 relay because it controls both fans. Hope this helps you out.

 

Well it turns out i checked out all the relays and they are all good... turns out i poped the plugs and the secondary fan works but the primary is a no go so im guessing the motor?

 

If you have power to the fan`s plug then it`s the fan motor itself.

 

Hey blazerman turns out i tested both fans and the primary fan motor on the driver side did not work and it turns out they turn on now ...question are they suppose to turn on with the ac though??

 

I think it depends on the air temp with the A/C. If you go to MAX the secondary will cut in but the primary will not till the engine temp gets on up there a ways.
