Hey guys its been awhile since ive been on but ive got another problem. my cooling fans stopped working again. ive checked to make sure i have power to the relays and i do i even bought a new relay to check with. i jumped the power to the relays to make sure my wires to the fans themselves wer good and sure enough they were. i changed the coolant temp sensor. nothing is working. i cant figure out why my fans arent kicking on when they should. all fuses are good too. i may have left some things out as im in a hurry atm.

You should have 2 power feeds to the relay. Do you?

ill have to check ive got three different relays. one relay runs both fans at a low speed and the other two both run the bigger main fan at a high speed. not sure how this sytem works right now. i would think one relay for each fan indiviually at a high speed and one for both at a low speed but, the indivdual fan that is run with either relay is the big one. it would seem as though the smaller fan cant be run independantly. you would think since im able to jumper the fans to kick on that my relays are bad, but i tested the relays for the audible click and got one. ill check the relays with actual continuity and resitance checks tommorrow as i only had one aligator clip earlier. but id think that out three used relays and one new one at least one would be bound to be good right?

It's a 2 speed system. Relay #1 is low speed utilizing #2 at rest and 2 and 3 are for high speed.

yeah i checked everything i jumpered the relays spots ont eh block and they ran the fans so idk what the deal is ive checked the relays and as far as i cna tell tehy work. i heard the click from em so id think they work. ive yet to actually open one fo the relays to check though. if the relays turn out to be good ive got a switch the previous owner had in the dash for some underglow lights, im just gonna hook the circuits up and have a switch inside to turn my fans on and off.

Second guessing what someone else did is going to be tough
