Is the cooling fan relay in the box under the fender next to the under hood fuse box?

How do you disconnect the electrical connector to the relays??? I'm not having any luck getting them to release??
TIA
^It looks like the 'ears' need to be spread a bit to get past the 'tangs'.
I just don't seem to have the magic touch to get these to release..... Is there a special tool you need to use or something??Quote:

Couple of finishing nails pushed up on those tabs finally got it to release.
Was a PITA.
Well kids it is looking like I may have been chasing Rainbows on my Relay theory.
Relay Checks out OK.
Yellow Wire from Relay to fan ohms out.
Black Wire Fan to Chassis Ground ohms out.
Hook a 9V battery to Yellow wire sometimes ya get fan sometimes ya don't.
Decide to back-probe the Fan connector with a T-Pin and I can get the fan to work everything I give it 9V.
Haven't taken the Connector apart but odds are good that is where the problem lies. ::Rant::
What rainbow (:cat:) are you chasing exactly? Car running hot?
No drivers side fan. Must had died near the end of the day Saturday she was fine until after 8th run heading back to Padock. I think that was the last time the fan worked. ;-)Quote:

If you cross the wiring, does it work?
Yes and No. That is the issue.Quote:

The cars wiring doesn't always play along. If you check voltage on the yellow wire which is the one that powers the fan it goes live as soon as the car gets to around 210 degrees. But not completing the circuit to ground.
Pretty darn sure it a break in the wires in the connector at the driver side fan, but I'm freaking melting so I'm done with it for today.
Looks like this connector got a bit warm. This is the connector that plugs directly into the drivers side fan.

Looks like the "Heat" got all the way in the fan motor as well.
The fan will run when hooked to voltage. But I'm beginning to wonder if it wouldn't be a bad plan to change it out as well?
I can't see your pics from work, but if it's melted, replace!
I'm thinking the same as you. I am a bit surprised it never popped a fuse.Quote:

Which brings another question : Do you get a used Fan Motor or do you just get a new one at $174.91? (p/n B6MC-15-150)
Used many be no better than what I have now but my TCB sees the price for the new one........ ;-)
How long are you keeping the car? How much do you enjoy working on it?
Well it has been on the lets get rid it list for a few years but we still have it.... I don't mind working on it since I had a Triumph TR6 in my youth. So I have experience Lucas / Mazda Electrics. ;-)Quote:

I might have a spare fan motor at home....are NA's motors different than NB's?
Thanks Sammmm from my digging looks like the NB fan motor is different than the one they used on the NA's....Quote:

They always have quality used parts. Never had a bad experience, other than his prices being a bit steep. Not gouging, just premium.
He seemed competitive on this project. Mazda has been raising parts prices pretty good over the past few years. Mazdaspeed Price for just the fan motor was $174.91 plus shipping.
Was pleased that he took the time to walk thought the problem I was having. Plus he never once lambasted me for being a really freaking old Millennial parts buyer. ;-)
+1 on Tom at Partsgroup. I rarely buy new when he has it. Easier than Nissan-Mazda heaven as the brown truck delivers to my door.
Replacement fan arrived today! Plugged it in and it worked then after a little while it didn't work....... Wiggle the connector and could get intermittent results.
Spliced in the replacement electrical connector and it stays working! (So far ;) )
So if you have an NB and the fan connectors look toasty and your fan is flaky you may want to consider replacing the connector also.
Also added some dielectric grease since I got a feeling water and or crud may have played a part in the failure due to the way the connector hooks into the fan.
What does Dielectric grease do you may ask:
481 miles of testing including a bunch of Stop and Go traffic Texas weather with the A/C on gauge never moved past 1/2!
Even got trapped on 35 tonight for an extended period on the way back from Huntsville (Went to see the Wife's family) gauge never moved. ::Banana::
