'95 Explorer blower motor won't work

We've got a 1995 Ford Explorer and the blower motor quit one day all of a sudden. Of course it was humid and raining and putting the windows down only drenched us... anyways... The blower motor works when wired directly and a brand new motor still does not work when it is plugged in to the original wiring harness. When we tested, there was no current coming to the plug to the blower motor (only +positive), but there is current going to the resistor wiring harness. We pulled out the resistor and hope replacing it will work. I think we checked all possible relays & fuses. Is it possible for the resistor to be the problem even if the blower motor doesn't work on high or any speed at all? Where do we get one? Any thoughts about what else might be wrong? Please help. Thanks, Kevin.

I dont have a wiring diagram for yours, so this is just a guess.

Since you do have 12 volts at the resistor, it sounds like your not getting voltage to the fan switch on the dash.

Or the ground wire to the dash switch could be open.

Or the switch might be shot.

BTW, the resistor is bypassed on the high setting, so replacing that wont help.

Ok, that kind of makes some sense. Thanks.

Whenever the dash fan switch is on the highest setting, there is a clicking noise...like a relay engaging...inside the resistor unit, but still the fan motor is not working...and not getting a ground for some reason. If the climate control system (ie. fan switch) is telling the resistor to engage to high and give the blower motor the negative power and it's not working, where do you think my problem might be? Thanks! Kevin.

If thats a relay clicking, i have no idea what it is.

If I had a 95 Explorer, I would also have the Ford "electrical & vacuum trouble shooting manual." for it & figuring this out would be simple.

Hopefully one of the other guys will have this manual & can help you figure this out.

Good luck with it.

Be aware that the Explorers also have a fuse in the power distribution block under the hood. See the attached link and scroll down to the right picture.

I had the blower stop working on my '99 in the winter. I can't remember if it worked on high only or if it didn't work at all. Anyway I traced the problem to the connector at the resistor pack. Either the ground or +12V wire (can't remember which) in the connector had corroded to the point where it wouldn't conduct, and I couldn't get the connector apart. I ended up soldering a jumper wire directly into the resistor pack.

Ok here you go:
Blower motor wiring diagram from a '99. Should be similar for other years

This is the pinpoint test for troubleshooting when the blower motor does not operate for 95's:

Turn ignition switch off.
Ground Circuit 261 (O/BK) at the blower motor.
Position function selector **** at FLOOR and turn key to RUN long enough to check for blower motor operation.

Does blower motor operate?

Yes
CHECK CIrcuit 261 (O/BK) between blower motor and the splice to blower motor switch and heater blower motor switch resistor for an open. REPAIR as necessary.

No
Pull A/C control from instrument panel enough to gain access to the electrical connectors.
With function selector set at FLOOR and ignition key in RUN, check for battery voltage at function selector switch Pin 1 (Circuit 260 [R/O]).
Is 12 or more volts available?

Yes
Reinstall the A/C control.
With ignition key in RUN and function selector set at FLOOR, check for battery voltage at blower motor Circuit 261 (O/BK).
If you don't see 12 or more volts, REPAIR/REPLACE Circuit 261 (O/BK) between A/C control and blower motor.

No
Check for voltage at Pin 3 of function selector switch, Circuit 348 (LG/P).

Is 12 or more volts available?

Yes
TEST function selector switch for continuity in all switch positions. REPLACE switch if not continuous in all positions.

No
CHECK Circuit 326 (W/P) between fuse panel and A/C control.

Smile blower motor controller change fixed the problem

thank you all for helping me with this problem. Based on one suggestion I changed the blower motor controller and it worked like a charm. Took me a good 4 hours but saved a lot of money. A simple voltmeter to check continuity came in extremely handy to check the short in the circuit. Part was $130 and labor was well priceless since I did it myself.

blower not working on ANY setting

Iam too having this problem ('98 explorer 4.0L OHC 4x4). i have replaced the speed selection switch, under hood relay as well as the resistor. The relay wasn't the problem so put old 1 back in. the blower worked great for about 2 minutes. now it doesn't work @ all. the blower is good i hooked 12v/4.3A to it & it spun like a top!(i did this 2Xs to make sure i didnt fry it). i do hear the relay clicking on when i go to turn the fan on(engine off Acc. on) so that's getting juice. I'm sure, but not possitive, that there's current going to the resitor now. IF there's a short somewhere i cannot find it. i know that there was because it worked as i mentioned before.I really want to know if anybody has/can make a diagram for the resitor connector so i'll know what's what, i.e. which lead to test for actual voltage.

the only thing that is located in that area u described IS the resistor. if it's a different item caould you be more specific/picture?
