in this video I'll be showing you how to easily check your radiator fan and relay so you can diagnose over heating issues and bad relays #radiator #radiatorfan
Tested a 97 Rav4. Why do my fans turn ON when I unplug that fan switch and turn OFF when in short with a paper clip like u have done. Thanx a lot for the tutorial
My 16 Chrysler Town&Country works as usual but a little slow. I changed it with a Dorman brand and worked but noisy so I removed and checked it like you said. It doesn't spin. Is there something preventing it from going on?
A lot of BCM supplies a Ground command to operate the relays 12v is to the relays all the time. With car off. Apply a Ground to low speed relay and both fans turn on at low speed. Leave that in place then supply a Ground command to the other relays and they will turn on. This is for 06 escalade. The BCM fail frequently not out putting gnd command to relays
Is it normal if my cable already has fire with a test light when turning the car on, will this still work if i add a + cable on top of the already working + ? To explain better: I used a test light and there was no fire in the Sensor cable, I turned the car on and there is fire in the + but none when car is off, Is it normal that there is fire when car on? Will this thecnic of testing still work? If i add + on top of the already working + when turning on the car? Please respond thanks!!
My ac 30 fuse blows and stops the ac condenser fan. U think it’s a bad fan? It’s harder to turn w my hand than the radiator fan which spins freely by hand. I think the ac condenser fan is harder to turn and the 30 amp fuse just can’t take it. I don’t have a tester . But , all my relays do work
Both fans should spin freely with just the touch of a finger if they are not spinning freely, then they need to be replaced. You are blowing the fuse because it's working too hard to push the fan. I hope this information helps you!! I would recommend checking out 1A auto for the fan they are a good price and work for a long time
How is checking if power is getting from the AC cab switch to the fan different then checking if it’s getting power from the point of the thermostat sensor? Is it just a point in between that runs along the same line of wiring?
I think he's just a part changer, all he did was a direct test just to see if fan is good or bad, when you direct test to the battery to confirm if fan is good or bad that bi-passes the sensor , fan relay, and the control switch.
So if fan runs when you direct test it , them the problem is going to be a connection or broken or burnt wire, bad sensor,bad relay or control if it's the condenser fan. The cooling g fan doesn't feed from the control in the a/c control
