Rear Seat Blower Relay location/wiring diagram?

[Javier B]

Hey folks,
the rear seat heat/AC blower fan has ceased to function. Zero sound or anything. working fine then suddenly zilch. Since I'm having a couple of other electrical issues, I'm thinking its wiring issue, but can't find any diagrams or info on where the wiring goes to that blower motor. I understand there is a relay somewhere?
Can someone give some advice about the path of the wiring, this relay location, and what fuse is involved for this? If there are any super-gurus that know about this stuff, I have a short happening in my airbag system as well, which started possibly at the same time, so possibly this all is connected somehow? anyway, any advice here welcome. thanks!

1996-2001 ford explorer / mountaineer workshop manual (5567 pages!)

Here are some wiring diagrams, though I don't know if they apply to all 95-01 model years. Come to think of it, I don't recall where they came from either (j/k, was ebesc0h0st before it got shut down), apparently I was a glutton for collecting them about 4 year ago, but they've been more useful...

Manual or automatic A/C? I only have the more detailed wiring diagram for the manual, but see conflicting info because one 2nd gen diagram shows a relay for manual climate control rear fan, while the other doesn't. The next paragraph focuses on the one that doesn't have the relay so could be wrong.

Looking at the wiring diagram "air-conditioning-manual-a-c-circuit-1-of-1.pdf", I don't see a relay for the rear blower for the manual A/C, just fuse #6 on the interior fuse panel, then straight to the blower (so with engine running or key in run position, should have 12V on a wire to the blower relative to chassis ground), then through a blower motor resistor (except on high speed so if resistor was blown, should still have high speed unless a connector/contact issue there or thermal fuse in that module is blown), then goes through the rear control panel, then to the front control panel. Wiring diagrams attached.

The automatic EATC A/C looks to be setup different, I can't see the fuse # on it but it's hot at all times instead of only in run, then a relay and I could only guess it might be in the box up under the dash to the right of the driver's footwell, or behind the radio if not there... IF you have one.

While a wiring issue is possible, I'd as soon suspect the motor itself or resistor. Use a multimeter to see where power stops, and you can also jumper a 12V run directly to the motor to test it but remember that in case the motor is shorted out, you're going to want a fuse on that run to it. If the existing fuse to it is blown, I'd also suspect a motor problem but since you feel you could have a wiring issue, a frayed wire shorting out could be a cause too.

I've also attached the workshop manual pages for a '99, hopefully it's the same. I also found the workshop manual wiring diagram for a '96, pictured, but can't figure out how to export the series of pages in that older manual. Ugh, what a pain that old workshop manual is to use, can't even read the icons to navigate it, too small. At least I can see on it that the fuse is #31, but remember these are all for '96, and '99, not sure if anything changed after '95.

The workshop manual might mention where the wires physically are, but I bet they just run through (under) the middle console stack and up to the dash head unit controller and relay box mentioned above if there is a relay.

THANKS! It was Fuse 31 ! I also had the diagram that showed the rear blower being Fuse 6 and no relay, so this one was the correct one, and problem solved! Works fine now. Love a simple problem! Yay, thanks group.

Glad to know it's working but odds are fair that if a wiring or motor problem, it could end up blowing the fuse again.
