Passat (B5) :: 2000 1.8T - Blower Fan Runs And AC Works But Heat Is Non-existent
Oct 13, 2010
So, for a couple of weeks my g/f's Passat has had no heat. The blower fan runs and the AC works but the heat is non-existent. Fast forward to this morning and now all of a sudden her heat miraculously works again. The car has 170k miles on the clock and had the timing belt and water pump done around 120k miles. The thermostat I'm not too sure about. I don't know when (if ever) the system has had a coolant flush so I plan on doing that this weekend. Is it okay to use something other than the G12 VW originally put in it?
At first I thought maybe her heater core was clogged but if it is I don't understand why the heat would start working again. Any tutorial on how to flush this motor properly and how to access the heater core lines so I can try to clear it? On my car it's a piece of cake but her VW stumps me sometimes.

2000 Chevy Monte Carlo... The heater/blower only works sometimes, usually not at all when it's freezing out. when it's a little warmer out, it tends to work more often, but still not all the time. what could this be? my husband tried replacing the blower motor, but that didn't change the situation, so he put the old one back in, and is now puzzled ?

Have no heat, the a/c works fine, ran the diag. and got codes 1262,1265,1947, and 5041, I don't even know where to begin.

So my AC only works on 4 (no 1, 2, 3). I replaced the resistor as is often the culprit. NOTHING. Still only works on 4. So I unplugged the resistor all together, still only works on 4. So, either my new replacement resistor is also bad (unlikely), or it's the blower motor.

97 passat vr6. I only get warm air from the vents when I'm accelerating. As soon as I come to a stop it starts blowing cold air. Does this mean there is air in the system? If so how do I bleed it out?

The car is a 2000 passat v6 with ~135k, auto trans. Well when the car is cranked it takes a bit to get running and once it does, black(wet) specs come out the exhaust and go all cover the surrounding area of the tailpipe. When the a/c is off it almost sounds like it is running normal but when the a/c is on(at idle) the engine runs very rough, it almost sounds like a misfire. It does have a check engine light, but i have no obd2 scanner, and from what i've been reading might not even do me any good because of vag com?

In my 2000 V6 Passat...I noticed that my temp gauge sporadically works...more often not. Is there a fuse or something that controls it?

I have a 00 Passat 1.8T and the blower fan for A/C and heat has been intermittently squealing. I can sometimes get it to go away by changing the speed of the fan but I was wondering if there is any way to lubricate it up. Or should I just be looking for a new fan.

My neighbors brother has a 2000 Passat v6 4 motion. (Climatronic) Here's the issue... the car has NO HEAT!!! and its cold out side. Last night we tore the lower dash part down to see the air box, when you adjust from hot to cold the servo is moving but were not getting any heat at all. The hoses going into the heater care are hot... there are no leaks.... also tried changing the climatronic unit itself and got no where.... I have a 3 hr drive home later this afternoon.

My mom has a 1988 350 Econoline van chasis that is a motorhome class C.
The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.
I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.
I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.

I have a 2003 Camry XLE (4 cyl). The heat will only work when the A/C is on. If A/C is off, air will blow from the vents, but it is not hot. What part needs to be fixed/replaced?

So after replacing the entire clutch assembly, coil packs, plugs,valve cover gasket, thermostat housing, blah blah blah basically a tons of new parts. I get her up and running and notice my heat only works when under throttle...yup water pump...but wait what's that milky substance under the valve cover cap now never ran hot but appears to have blown the head gasket as well. Doing compression test this weekend..

I have a 1992 Mazda 929 in which the heat does not work while the a/c does work perfectly. When the problem first occurred the fusible link for the A/C was broken (indicative of some electrical overload). I replace the fusible link and still no heat.
I went under the passenger side of the dash and changed every visible black box (fuse/sensors)that is attached to the heater core unit. After that the heat still did not work.In relation to this problem the care now runs hot whenever I am a red light or in stop and go traffic.This seems to me a that a mechanical gate from the engine is not opening to allow the hot fluid from the engine to get into the heater core.

I have a 2005 Hyundai Santa Fe 3.5 litre 4wd and am having a crazy problem. It has the automatic heating and air conditioning module (digital). The heater fan comes on as soon as i start the engine and runs in the 2nd highest speed. I can adjust it so it goes one speed higher but never lower than the one it comes on at and cannot shut it off. It operates the same under heat OR A/C modes. The temperatures adjust o.k. but it is always on. Where would i find the a/c control module? Could it be the transistor or resistor and where are they located?

My blower motor runs with the key out on all speeds in my excursion. Replaced blower relay in hood fuse box. NO FIX. As I move climate selector to off and turn key to acc. and off it will turn off the blower. If I turn the selector to any position such as vent or heat with the key out, blower runs thus drains the battery. Do I have to replace the whole climate pod?

The blower fan works just fine, when i put my hand up to the vent i can barely feel air coming out, but something is blocking it. this is for all vents (floor, windshield and all four vents on dash).

So for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.
Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).
How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.

My wife has a 06 Sonata with the Manual AC controls. The blower motor works intermittently. Sometimes it works, other times it does not. It does not matter which setting the HVAC is in. Yesterday while driving it, we went over a bump in the road and the motor started running again. Since the motor runs, I want to discount the fuse and relay.

I have a 1996 Ranger that the Heater/AC blower only works when the outside air temp is above 45 degrees. I have replaced the relay, and the blower motor resistor. What could be causing this?

I'm having issues with my 09 Camry. Yesterday my water pump shoot craps on me. SO this morning I replaced the water pump. After replacing the water pump I noticed that the heat would work only when the car is moving. So I went to the store again and bought a thermostat. Replaced that and the heat still only work when the car is in motion. So I checked the radiator cap it was bad I was able to hold it in my hand and spend it with the other hand. Ok replaced the radiator cap. I let the car sit at idle running and the heat worked shortly then it started to blow cool again. I checked the radiator hoses and the lower hose was cold right along with the thermostat housing.
