Radiator fans not coming on

My radiator fans don't come on seem like a lot of pressure in the cooling system. I have a similar problem with my Suzuki Forenza 2005. The radiator fan is not turning on. Did you fix your problem? How? Do you have a wiring diagram for the car or manual?

Thanks

Hello,

It sounds like you have one of three things that can be wrong but with a few easy tests we should be able to figure it out. First would be a fuse next a relay and third the fan motor is no good.

Here are a few guides and diagrams to help us get started.

Here are the diagrams (BELOW)

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

Which wires are the positive and negative wires for the
Cooling Fan Relay Switch for the driver side cooling fan
On a 2005 Suzuki Forenza so that I can directly hook the cooling fan to the car battery so that the cooling fan will come on to keep the car from overheating

Repost I will not do that due to the chance of a fire. Maybe someone will but I doubt it.

My fans quit too. I followed the diagram on the earlier post and found a bad relay. Replaced it for about $25.00 and its back on the road
