Cooling fans

[Guest]

So I’ve got a weird problem, my fan 1(low speed I think), won’t come on, I’ve checked all of the relays and fuses, jumped relays, replaced the temp sensor and still can’t figure it out, I can turn the ac on and get one of them to run but the other won’t, also brought power directly through the relay and both fans would run, any help would be great, thanks

I need year make model and engine info to look at the cooling fan system. Why do you think you have a problem with the fan? Is there a problem? Do you have access to a scanner that can view the engine data?

If you have a low speed fan and a high speed fan operation there should be at least two relays to turn on the fans. With the car info I can look up the fan wiring diagram.
