Great video and information. I pulled relay out of my vehicle, gave it juice, and the fan turned on high speed while relay was on work bench. It was like my car parted the Mississippi river then decided to walk on the water to cross anyways.
Thaaaank you soooo much chief. You've helped me fix my car.. Exact same relay it turned out that pins 6 & 7 are not connecting in both relays after applying power.. I disassembled the relay and found burnt mark on a metal which made a big gap comparing to pins 3 & 5 that's why they wont connect.. So with a little pinching to tight the gap more and now relay is working great. My issue was : one fan only runs in low speed and stops when high speed kicks Thank you for the video once again 🌹 🌹 🌹 🌹
One important thing to note, if you want to use a multimeter to do continuity test in your home, make sure power is off. You can trace switch and outlet wires doing continuity test, but power must be off.
Great one of my nissan sunny fan relay was not working properly.when i test one of the switch pin 4 and 5 pin was no contact only 6 and 7 has contact.Can this problem cause overheating?
hi and thanks i have a problem with tha fans , when i turn on the a/c, they start but slow !! ,,,, (they are not Hi and Lo speed) ,,, and when the a/c is off, and the car reach temperature the fan runs fast and great !! i dont know what it is can you help me, thanks again
My radiator fan relay is clicking over and over really fast and my fans are on. Does that mean its bad? My radiator fan fuse blows every single time I drive it usually right as soon as I get home... got new radiator fans but I need to know if its my relay or the old fans to see if i can save my money
All of the diagrams I've seen on this 3 fan set up, relay number 1 is for the AC fan. Seems odd that relay 1 is shown for the Radiator. But you're working a Nissan - my diagrams are for GM cars/
I have a Chevy cruze. My engine cooling fan runs constantly at high speed. I've changed temp sensor, the fan itself, the thermostat and even a/c pressure switch, it didn't fix the problem. What could make the engine cooling fan running at full blast? I appreciate your reply.
I get continuity but it's not continuous I put power to it continuity take the power off put the power back on no continuity it's hit or miss with the continuity does that mean I need to replace the relay
watch video, follow diagram on relay BUT if relay(s) are like the ones I oulled out to test, there are no numbers or writing on them at all. Cheap as5 foreign parts FiatChrysler uses ! I'm going to guess. Hope I don't mess up good relay,..Auto Zone lists them at $66= !! Maybe I should go to auto Zone and see how terminals are numbered on the part they have. Hmmm ?
This isn't always true. You can have complete continuity and it still can be bad. A good one reads 40-80 and he doesn't tell you in this video. If it's higher than 80 it's going bad and lower than 40 it's bad.
I have a 07 Pontiac G5 2.2ltr vin-F. Its the same as a cobalt, Saturn ion...my cool fan 1 & 2 use a 0329 relay, THEY ARE BOTH 4 PIN RELAYS. The control or, (the one that just says COOL FAN), ITS A 5 PIN BUT, ITS MISSING & I EVEN CALLED THE DEALERSHIP & THEY SAY THAT THEY ONLY FIND 2 RELAYS FOR THE COOLING FAN THERE BOTH THE 0329 WHICH ARE 4 PIN RELAYS...THE CONTROL SICKET HAS 5 PINS...I HAVE TESTED IT BECAUSE, I realized that, when I ground the top left peg of the control relay socket, the fan comes on but, the 5th peg then receives power. One row, top rowhas 3 legs, & bottom leg has 2 lines. Most other of the relays are 4 pin except 1 or 2. I am at a loss & I do not know what relay to use? & SUMMER IS HERE! ANY HELP WOULD BE GREATLY APPRECIATED!!!!! THANK YOU!!! The cool fan 1 & 2 use relay 5510-0329...
Ohm testing is not a foolproof test during working conditions because of heat or wear in the contacts and the possibility of intermittent failure. In other words, it works then it doesn't work. I swap a known good relay from same car if available, quick and easy. If you pull a part off a junk car, grab some relays and fuses and toss them in your tool box. No guarantee they are good, highly unlikely to be bad, but I have gotten bad parts from the parts store too.
To prevent corrosion, rust and or oxidation on, relay pins junction box holes, connection, battery posts, wire or cable terminals and junction box hole ,,, ''' apply / add dap of silicon / dielectric grease . Also, it will ease insertion & removal of relays, fuses and any component that has pins and or legs.
1 question, M Aar. For some reason I thought, in addition to doing all the things you listed above, that dielectric grease was supposed to enhance electrical connections & promote the flow of electric current. I recently bought a tube & applied it to the ignition switch in my new/used Ford Ranger truck. I had/have problems...but they were coincidental after I cleaned the grease off and read up on it. Turns out my 20-year-old Ranger thought (& still thinks - I haven't been able to drive it in 3+ months! Grrrr!) that somebody was stealing it, so it engaged the anti-theft system. Dash is dead/black with the word 'Theft' in red blinking when the key is inserted. ($75 per key for the dealer to re-program, reported by some...) Well, my question is/was: is there such an electrical grease that protects AND promotes current? Or...I'm afraid I'm way off base(!) TIA!
Good video.!.Most likely, I would have lost my temper, and used a 3 pound hammer to "remove" the relay...lol. Kidding..but sometimes!. .Man electrical problems can be a pain !
THANK YOU!!!!! So, of your relays are good, fans come on with ac, temp sensor is new, but fans won't cycle on when car warms up; what's left?...faulty ecu, right? And if so, is there a test for that? Thanks. (94 Sentra 1.6)

By far the clearest, most easy to understand explanation.
Your nice and patient . I like teachers like that
Thanks... You can teach, easy to learn from and straight to the topic.
Great video and information. I pulled relay out of my vehicle, gave it juice, and the fan turned on high speed while relay was on work bench. It was like my car parted the Mississippi river then decided to walk on the water to cross anyways.
Yea, right.
Not a bad video it does help you know you get a little bit understanding what you're dealing with
Saved me money, as I did not throw in new relays when they were fine. Thanks for very clear instructions!
Excellently explained. Thanks!
Exactly what I needed to know thank you
Thanks so much. Thank to you I learn every thing about relays in quietly episode with great intention from you. May God Bless You.
Thank you. Glad to help.

Very informative, thank you for sharing!

Thanks for your videos
More detail about the exact prongs to place the alligator clips on, please. For the high speed and low speed test.
Thank you. Very helpful.
Very good the way you've explained thanks a lot.
Yeah my vehicle only has two relays one for high and one for low but the video is very helpful and I give you an idea what you're dealing with
Great one of my nissan sunny fan relay was not working properly.when i test one of the switch pin 4 and 5 pin was no contact only 6 and 7 has contact.Can this problem cause overheating?
Nicely explained!
I have the same car. The ac side fan takes a while to come on about 5 minutes. Do you think it's the relay?
Nice job
Very nice
Looking like Wolverines Half AMerican Cousin for a minute there bud..lol.. Great vid man!
Thank you sir
AMAZING THANK YOU
Overall very informative! Thank you so much!!
Thank You
I have a 2016 Nissan versa note sv. Where is the fan relay located? My fan doesn't come on at all.
Very informative video dear friend thanks
Thank you sir !
Great Stuff! I need help with the following. Electric radiator fan on my Nissan D22 doesn't work. Aircon is ok. Rlays, fuses and fan ok. Thanks.
Whay have maxima after 2000 only highspeed ralys and run all time from cold engine ?
Great video. Thanks for sharing.
Glad to help.
hi and thanks
i have a problem with tha fans , when i turn on the a/c, they start but slow !! ,,,, (they are not Hi and Lo speed) ,,, and when the a/c is off, and the car reach temperature the fan runs fast and great !! i dont know what it is
can you help me,
thanks again
So what if only 1 fan turns on? Aren’t the supposed to work in tandem?
My radiator fan relay is clicking over and over really fast and my fans are on. Does that mean its bad? My radiator fan fuse blows every single time I drive it usually right as soon as I get home... got new radiator fans but I need to know if its my relay or the old fans to see if i can save my money
My car's manual says that continuity must be open if charging relay with power. Mazda 626 1995.
Great. Thank you
Thanks for the video.
Welcome.
Driver side radiator fan runs hi speed , passenger side doesn’t come on at all and no low speed on both. So should I replace relay fan 1 & 3 ?
Nice i learn alot..thanks..
Excellent thank you. 🐧🐉
Thsnks
All of the diagrams I've seen on this 3 fan set up, relay number 1 is for the AC fan. Seems odd that relay 1 is shown for the Radiator. But you're working a Nissan - my diagrams are for GM cars/
I cannot find my relays at all! My car seems to have an aftermarket fan so they appear to be elsewhere. Any tips for looking?
I have a Chevy cruze. My engine cooling fan runs constantly at high speed. I've changed temp sensor, the fan itself, the thermostat and even a/c pressure switch, it didn't fix the problem. What could make the engine cooling fan running at full blast? I appreciate your reply.
Your ambient air temp sensor it’s for the temp outside of car
Great video!!!
Hope it helped.
I get continuity but it's not continuous I put power to it continuity take the power off put the power back on no continuity it's hit or miss with the continuity does that mean I need to replace the relay
How do you know which ones you are supposed to put the positive on vs the negative?
watch video, follow diagram on relay BUT if relay(s) are like the ones I oulled out to test, there are no numbers or writing on them at all. Cheap as5 foreign parts FiatChrysler uses ! I'm going to guess. Hope I don't mess up good relay,..Auto Zone lists them at $66= !! Maybe I should go to auto Zone and see how terminals are numbered on the part they have. Hmmm ?
I'm a big fan. My fans don't turn on high even when my ac is on. The wiring is good it just dont get the signal to turn on at high speed.
My fans work on low speed when I turn ac on but they dont kick on when I'm at idle causing engine to overheat when I'm not driving
Can I use a 12v battery on the car as my source of power for terminals 1&2?
I don't recommend it. Your better off having an external battery source.
great video, easy peasy, thanks a bunch...
Very helpful clip
Many thanks 2 U
Thanks for watching. Cheers.
Good stuff
Thanks CarsNtoy
Glad to help.

Are you talking about ohms?
@@countryfella94 yes
How do you identify 1 and 2 ? Or any of the prongs. are they numbered on prong side?
They're typically labeled along with a diagram.
How do I tell which pins are which at the back of the really.are the pins marked with numbers.

Nice
what rc battery pack voltage would you recommend
Cars run on 12 volts so you'd want something in that range
To prevent corrosion,
rust and or oxidation on, relay pins
junction box holes, connection,
battery posts, wire or cable terminals
and junction box hole ,,, ''' apply /
add dap of silicon / dielectric grease .
Also, it will ease insertion & removal
of relays, fuses and any component
that has pins and or legs.

Me puedes decir donde está localizado él censor evap de nissan central b13
Did anyone else’s butthole pucker just a little when the alligator clips made contact with that screwdriver around 7:15?
God bless you a great deal!
Good video.!.Most likely, I would have lost my temper, and used a 3 pound hammer to "remove" the relay...lol. Kidding..but sometimes!. .Man electrical problems can be a pain !
Great
if they all 3 don’t make a beep sound what that mean that they all 3 are bad?😭🤣🤣
Power probe
Absolutely. However, most people won't spend that kind of money for using it one time. Cheers.
