Radiator Fan Problems

my radiator fan stopped working bout 6 months ago so i replaced the rad fan switch and it fixed it, now it has stopped working again, i checked the fan motor and it is good. is there any other sensors or switches that control when the motor kicks in? or do you guys think that switch just went out again?

Um don't know its possible but doubt it. You may have a wire that has broken inside the insulation. I would start somewhere close to the switch and bend the wire to see if it makes contact and comes on. I had a similar thing with a dimmer switch in one of my older cars a few years ago I changed out the switch and it worked like a couple times then quit. It was hard to find because the wire looked fine but was broken in two inside of the insulation. Good luck I hope you find the problem.

Sorry to go off topic, but, can you increase the speed of the A/C fan? I replaced both of the stock fans with Fluidyne ones and the A/C fan spins much slower than the other one. The stock fans are physically different, as far as the blades go.

Okay so you want to speed up your radiator fan because your A/C fan spins slower? I'm confused (I don't think I follow your question)

Did you mean you want to speed up the A/C fan?

Also I think the speed of the fan is controlled by the motor and I believe your fans came with motors?

The rad and AC fans are the same aren't they? do a qiuck test if you can, plug the rad fan connection to the ac fan, see if it turns on.

Yeah, I phrased that horribly, now fixed.
