Prius C :: Heater Blower Not Working When Cold Outside
Feb 12, 2014
I have a 2012 C 3, with 27K miles. This morning on the way to the store i turned on the heater and the fan turned on and after like 2 mins the blower stop working. All the lights are on, but nothing comes out of the vents under any circumstances. I tried taking of the ECO mode, I tried turning the car on and off. still nothing.
If I bring it to the dealer will they fix it under warranty? Could it be a bad fuse? where is the fuse box? What could it be, its freezing outside and I need heat for the kids in the car.

The car is a '99 Volvo V70 XC AWD. The blower for the heater wasn't working this morning. When I left work it was blowing a little but not as high as it should on full.

I have a 1990 Mercedes 190E with kind of low miles for its age. Nice car, runs well. The problem is that the blower for the AC, heater, and defroster won't go on when it's cold or wet outside. Sometimes while I'm driving it will suddenly turn on. Sometimes if I restart the car it will go on; sometimes stays on, sometimes goes off after a bit. When it's dry and/or warm outside - no problem; on whenever I want, stays on, no problems. I have checked and replaced the fuses and I have had it at three different repair shops and they all insisted that it was the center console control that was causing the problem and now I have that whole unit replaced and it has not fixed the problem no matter what I tell the mechanic. I get it that it's an intermittent problem making it harder to identify ...

So I believe I have glitch in my blower system. When I have the car and heater on, it comes through, but it feels like the blower isn't working much at all. however, when I but the car in reverse or hit the windshield wiper cleaner, the blower starts doing its job like it should.

AS topic states, it just stopped working on my wife's drive home from work... I believe the fuse is the 2nd one from the top.. far left... I checked it, and it's in-tact...

I have a 2004 Elantra. The blower for heat/ac not working. I did all of this:
Checked interior fuses, all OK.
Checked 30 amp fuse in engine compartment, put a new one in.
Pulled blower motor out and tested with a 12V power supply: worked fine.
Replaced Blower Relay
Replaced Blower Resistor
all of this and still no blower.
The heater control panel on the dash has 3 knobs. When I turn the first to AC...the light comes on and I hear the AC kick in. 2nd knob is blower fan...nothing on any setting. 3rd knob...hot and cold...not sure since no blower.
I am lost at what to do next.

Well, as the cold weather has approached, a minor issue has surfaced.
It appears my driver-side mirror heater is not working. Both mirrors still move as they should, and the rear defroster and passenger side mirror both heat as the should with the defrost button, but the driver side does not, as it is cold to the touch and naturally did not melt the frost yesterday.
I looked at the fuses hoping it would be something as simple as that, but it does not appear there are separate fuses for each mirror; the naming is a bit cryptic, but it looks like there may be one for both mirrors, which logically would not explain the situation.
Seems to me the heater itself is defective, and I am not exactly looking forward to opening up the mirror and/or spending money to fix this...
The Prius is a 2006, and I am up to 256K KM (~160K miles) to date.

I got a new resistor since my last one was in a puddle of water and installed that today and still have no heater blower motor. I checked all the fuses and have power. I sent power to the blower itself and it spins good. So somewhere between the fuse and the blower it isn't working. I need to take the controls out and test for power there. Didn't have time to do that today. What wires to check or where to start trouble shooting?

My blower on my 2010 Lariat truck isn't working and I can't seem to figure the issue. No heat or AC. It seems that some air is coming through, and the fan indicator shows it on high, but nothing.

I have a 2005 Dodge Caravan with a heater blower that doesn't seem to be working. Whether the heater knob is on low or high, it does nothing, but you can feel a little heat coming out, though. I was told it may be a resistor behind the glove box. I've already checked the fuse, and it seems OK. What do I do?

The heater/ac blower stopped working on my 2004 Lexus GX470. All the lights and display work but the fan doesn't work on any speed. I replaced the relay in the fuse box under the hood but no luck. I removed the blower and it works when I hot wire it to the battery. I checked the voltage coming into the blower and its at 13.5V, same as coming off the battery but it doesn't turn the fan.

My heater/AC blower quit working. Does not work with either heat or AC. I suspect a blown fuse but cannot find one for the blower.

I had to replace the vacuum control for the heater in the dash panel. The fan worked good on all 4 speed settings but only in the defrost position due to the damaged control valve. The control valve works all position for the heater positions now. There is power at both sides of the heater fuse under the dash but no blower function. Is there a fuseable link elsewhere in the system to check. Is the fan motor only accessible to test by accessing the heater/AC under the dash on the passenger side. 1973 Crew Cab....

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.

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.

247,000 miles on '98 Toyota Camry as of last summer, car owed us nothing. Suddenly lost oil a month after regular oil change, ruined engine. Mechanic found used engine from totaled car (w/ approx 65,000 miles). Current problems:
1. speedometer/odometer not working,
2. heater/blower stopped working this week, blower makes a LOUD, HIGH FREQUENCY sound, sort of like a siren.
Was hoping to get another 2 years from her considering recent cash outlay. The mechanic couldn't figure out issue #1, and he hasn't looked at it since #2 started this week. I guess we can live w/ issue #1, but #2 has to be fixed ...

Very strange things happening with 2009 F350 Gas, first the heater blower only is now working on high, progressively has gotten worse, low settings started not working a while ago, now only high works. Just recently the strangest thing, start the truck OK, turn on radio OK, turn lights on then the radio goes off. Will bring it to dealer in a day or two if I can't figure this one out.

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.

Purchased 2011 Prius 2 with 108500 miles on 4/29/2015. Didn't fully check all climate control settings and fan speeds. Two days later, car had vibration and rumbling sound which was increasingly severe on three highest climate control fan speeds in all modes (e.g. AC, heat, auto, manual, etc.). Sounded like a quiet lawnmower on highest fan speed. Was quiet on three lowest fan speeds. Glove box and passenger side dash vibrated in sync with noise.
Cabin air filter had been replaced by a large Toyota Dealer as part of pre-sale prep. I suspected filter was not installed properly. Removed glove box and filter, which had been properly installed. Vibration/noise were same when fan was operated without filter or glove box installed.
Felt around inside of fan housing. There was debris, including seven pieces of acorn shell (see image below). The concave sections of the shells were firmly wedged in the fins of the squirrel cage (no pun intended!) impeller. Cleaned out all nuts and debris, reassembled, fan operated quietly without vibration at all fan speeds.
The shells essentially unbalanced the impeller and induced vibration at high fan speeds, just like an unbalanced wheel would induce shimmy or vibration at freeway speeds. What is baffling is how the debris and acorn shells this large got past the filter. Filter fit on the right side is pretty good since a plastic flange goes between the pleats. The left side appears to have a looser fit with some gaps.
