Ford A/C :: 2003 F150 - Blower Motor Stopped Working All Of A Sudden
Sep 25, 2014
I've read quite a few threads on this subject and came across the resistor, fuses, and relays. I have some fundamental testing procedure questions.
1. To test the resistor, it says to back probe the brown/orange wire to check for voltage. So I'm assuming I would hook up my positive lead, here?
Do I really need to hook up the black lead all the way to the negative terminal on the battery? Just with a long extension? Or is there somewhere else I can hook the black lead to? (I know, how dumb!)
2. I downloaded owners manual, but I can't seem to find a fuse or relay specifically for the blower, so what fuse and what relay is it?
3. In the Haynes manual, it says locate the blower motor relay, in the relay box under the center dash panel, where the hell is that?
4. Do I need to remove the glove box to access the resistor and blower hosting.
5. Anything else I should know?

I have a Full Size 93, 5.8L Van. The blower motor has stopped working. I have checked the fuzes, ok. I have checked the Power Distrubution Box, ok. I do have power to my Aux (rear) blower. I have hot wired my blower motor, it works. I have no power to the blower motor, thermal limiter, or to the fan control switch on the dash. (Like I said, the Aux on the dash works). What else is there?

Well, let me rephrase that, the AC works but blower motor doesn't. When you put your hand up to the vents, they're cold.
Long story short, I ran my AC on MAX on way home from work, driving time of approx. 35 minutes. I got home, showered, and got back into car to go downtown to store. It was then I discovered that the AC wasn't coming on, and it was still on max. I shut it off and turned it back on, but to no avail. I checked all related fuses, or at least what I think is related and checked my "Taurus Bible" the chilton manual. I swapped out a blower motor relay and it didn't work, but i'm not sure that relay was or was not good, it was out of a '96 E-250 at work.
So now I get out my test light. I pulled the connection from blower motor, connect it and turn on AC and light comes on. Vents are getting cooler. So I get my tool and pull the radio and climate control assembly. I pull the plug to the actual fan connection, the part that connects to the fan switch that controld fan speed. I'm getting nothing there.
Is there a relay I don't know of? I know the AC still works because vents are still getting cold, but I can't get air to move. A LONG time ago it did this but "corrected" itself. What is my next step? I'm not sure what to check next and my repair manual is leaving me in a boat with no oars.

Turning the fan knob yields no results. The AC compressor does kick in as I can feel it when I turn it on when idling, so the knob appears to work. The blower does not move air.
I checked the fuse below the steering wheel and the fuse makes a complete circuit although the edge looks a bit darkened. Other fuses from working devices look the same and I took a spare 10A fuse from the designated area and inserted into the blower motor fuse location - still nothing.
I will also inspect the relays/fuses in the engine compartment to see if anything in there looks blown that's related to the blower motor. Hopefully it will be something simple, but probably not...
I will need to take it in to get it looked at and fixed, and this is probably not under warranty since vehicle has 56k miles... while I'm there I'll have a transmission fluid exchange done as well and I was planning on getting some body work done.
My bumper was torn off from the fact that it sits low enough that sometimes it would go over the parking stump. Well, it eventually got caught really bad and tore it off. Now the tab where the screw goes to secure the bumper has sheared off so it just hangs. Also, the tearing action from the parking stump caused the inner fender to come off and rub against my tire while driving, tearing it into shreds from the friction.

I own a 99 Suburban 1500 5.7. The front blower motor stopped working on all speeds so I replaced the resistor, it still did not work. I then replaced the speed selector switch and it started working fine. Three days later I smelled a slight electrical burning smell and the fan stopped working again. I plan on replacing the switch again to see if that is what went bad. Whats causing this to happen? Maybe the motor is going bad and causing the switch to short?

My blower motor in my Jetta recently stopped working. When I turn on the blower it works for 10 seconds or so then slows down and dies. Is this a blower motor or resistor problem?

Got a 2008 Hyundai Accent. Yesterday, the blower motor just stopped working. I had just started it up, the heater came on for about five seconds. There was no noise, no funny smell, nobody had done anything to it. It just stopped. I checked the ac fuse and it looked fine. I looked in the fuse box under the hood, and I'd like to check the fusible link for the blower motor to see if it has a problem. Is this something I could do and how? Also is there anything else I can do to diagnose the cause of the problem?

The air conditioning blower motor stopped working this past summer (worst timing ever). I took it out, put it back in, and it worked again for a day before dying for good. So, I ordered a new one and replaced it. The replacement was working fine for about 5 months, but it then began exhibiting the same problem as the original: it wouldn't come on until after I'd been driving for a while. The new unit never made any unusual noises while running (the old one got noisy just before I replaced it), but now it isn't coming on at all. I find it hard to believe that the replacement blower motor has failed after only 5 months. What else should I check?

My air conditioning has stopped working and the dealer tells me the blower motor has frozen up. This car only has 73k on it. Is this common to the 2005 Touareg or ?????

I have a 2010 Toyota Camry 2.5L. Suddenly the blower-motor stopped working. I looked at the under-hood fuse panel and noticed a few of the fuses in the fuse bus-bar were blown, however I'm not sure how the bus-bar is removed. Is this most likely my blower-motor problem? If so, how do I replace those fuses?

My 99 f150 blower motor and blinkers slowly but surely went out on me. The hazards still work. I changed the flasher relay and the relay for the blower motor, and nothing. I've checked all the fuses, and checked for wire issues and nothing.

Recently bought a 2003 E350. The front heater/ac blower motor isn't working. I found the control switch melted and bought a new switch. Before installing it, I need to do some diagnostics. I checked the blower with a couple of jumpers ant it turns and blows. I think that leaves the blower motor resistor. Where it is on a 2003 E350? I also need to check the relay. I have a power distribution box at the front left under the hood. Is the relay there? The box is not labeled like my GM products. Which is the blower motor relay? Finally, which fuse controls the blower motor? I read it might be a 40 amp fuse. If so, that might narrow it down.

My 92 F-150 my heater blower motor doesn't put out enough air like my 2003 Lightning blower motor does.... So I figured after all these years that I would put a new heater blower motor in, well it's the same hear output and there's no debris in the heating ducts and the cable lever is working fine to close the blend door, so I guess maybe it's normal for these 92-96 F-150 trucks to have mediocre heating output ;-( Is there a bigger motor I could put in to get more heat..... The resistor is fine to, it works on all speeds.....

2003 F150 4wd with auto climate control. My blower for heat and AC completely stopped working a few weeks ago. I have checked all fuses, i replaced the relay under the dash, i replaced the blower motor control module. I supplied power to the blower motor itself and it ran fine with no noises. I ran the self test on the controller in the dash under the radio and it passed. I am not sure what else to try.

Our 03 Civic recently went into the shop for a rotor replacement and the shop did an oil change for us while they were at it. My wife got the car back and she immediately noticed that the "AC" wasn't working. After asking a few additional questions (I'm not in the same city this week), it isn't the AC that isn't working, the fan/blower isn't turning on at all. We had the same shop check it out again and their response was that they weren't anywhere near the blower motor so this just has to be a coincidence. I could accept that but I'm still worried about a scam.
The car was in the shop just to have the rotors put on, not an oil change but they did an oil change for us anyway. (I was going to change the rotors myself but I couldn't get the caliper hangers off and it was 100+ degrees outside so I decided to have the shop mess with it), Would it be easy to sabotage the blower motor on this car?

My driver's door power window motor stopped working. Replaced motor (Dorman). New motor was shaky and wouldn't stop when going down. Replaced motor again (Dorman), same thing. Regulator became damaged, replaced (Dorman), smoother, still won't stop with auto button, or holding down button. At some point glass came out of regulator and track. Replaced glass. Window goes up and down smoothly, but just doesn't stop when going down and tries to keep going. I don't see a limit switch or circuit for it. I see there is a relay and a fuse for the auto down. What tells the motor to stop driving current?

My HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?

I am trying to troubleshoot why my heater blower, cruise control and info center above my rear-view mirror has stopped working. I am trying to confirm power to an orange wire next to the driver-side fuse box. I have confirmed no power at the fuses. I am hoping the problem is the wire box below the fuse box and not the ignition switch. I have a wiring diagram and the power feed to these three fuses is via an Orange wire. There are two Orange wires in the box, I am trying to determine which one feeds the fuses for these three devices. I have a picture of the fuse box.

2004 Prius, 135,000 miles.
About a month ago, the blower motor stopped coming on all the time. A quick whack under the glove box fixed it when it didn't start. Then about a week after that, I felt like the AC wasn't really warming when needed. This may have been true earlier, but it hasn't been that cold around here, so I wouldn't have noticed, perhaps.
About a week ago, I start hearing what I might describe as a rattling kind of noise I had never heard before sometimes under hard acceleration. Not always. Didn't hear the noise tonight, for example. Of course, then, tonight, on the interstate, the warning light pops up for just long enough for the temperature indicator to flash up. It quickly disappeared, but in the remaining two minutes I was driving, it flashed up briefly twice more.
Now, in digging around on this topic, I've read about issues with the inverter coolant pump, and that there was a recall. How could I find some information on this recall? I don't remember ever having it changed, so I'm just curious what I might need to say to get that swapped out under a recall if appropriate.
Also, based on what I've said, does it seem likely that the issue is with that pump? It sure seems to fit the bill, but who knows. I'll be bringing the car in ASAP but I'd naturally like to be armed with as much information as possible.

99 Explorer Blower motor quit working. Disconnected and hot wired to a battery and blower motor worked. So I know it is in the switch and/or wiring. I need this truck everyday so going into the shop is out. Live in Northern Mn and the temp was -15 degrees. So as a temp fix what does everybody think of running a wire from the battery to a switch inside and then to the blower motor and then to a ground. Would have a inline fuse. If this will work what gauge wire and what amp fuse would you use. Its getting cold without heat.

Blower motor only seems to be working on the 3 & 4 position? Resistor bad? What is the location?
